(svn r15695) -Feature [FS#2672]: Allow the number of towns that will be generated in the generate world window to be customized.
Some warnings:
-the maximum number of towns to be accepted is set to 5000
-the minimum number of towns to be accepted is set to 1
-the number that is specified is NOT guaranteed to be the exact number of towns generated. The normal mechanism of town creation has not been modified. So town placement can still fail.
-setting a custom number of town will change your difficulty settings to custom as well

(svn r15340) -Fix [FS#2121]: changing town road layout in-game caused ugly road networks
-Fix: use a flag instead of TL_NO_ROADS to forbid towns to build roads. The flag is ignored during world generation, so there won't be 'ghost' towns anymore
-Feature: town layout is now stored per town, so it is possible to (manually) set different layout for each town

(svn r15027) -Merge: tomatos and bananas left to be, here is NoAI for all to see.
NoAI is an API (a framework) to build your own AIs in. See:
http://wiki.openttd.org/wiki/index.php/AI:Main_Page
With many thanks to:
- glx and Rubidium for their syncing, feedback and hard work
- Yexo for his feedback, patches, and AIs which tested the system very deep
- Morloth for his feedback and patches
- TJIP for hosting a challenge which kept NoAI on track
- All AI authors for testing our AI API, and all other people who helped in one way or another
-Remove: all old AIs and their cheats/hacks

(svn r14514) -Codechange: use 'size' instead of 'length' for querystring and textbuf, explicitly say it includes the terminating zero
-Fix: one couldn't rename things with too long default/automatic name
-Fix: buffer overflow in console when too long (1024 bytes) command was entered

(svn r14105) -Fix: Some typos that are more grammatical errors, as it seems.
Provided by ln
I've added a little fix on currency.cpp too, why not :)

(svn r14060) -Codechange: Replace numbers with Colours enum on Gen world gui.
Note that some WWT_TEXT widgets have received a COLOUR_x value.
It is not a valid colour a per say. THe strings been displayed there do have their own colours encoded.
IT is currently just for the sake of ease of writing, as TextColour and Colours are not really related.

(svn r13715) -Fix [FS#2129]: C-like strings had to be rebound each time they were printed, otherwise the text could change due to the few number of slots that could be used to bind.
-Codechange: remove all BindCString and related functions and replace it by RAW_STRING which prints the C-string raw pointer that is on the 'print stack'.

(svn r13256) -Codechange: merge the OPTS and PATS chuncks.
-Codechange: split the diff_custom variable.
-Feature: allow changing some of the diff_custom variables via the console in network games.

(svn r13251) -Codechange: rename _patches to _settings as that is more logic.
-Codechange: move all Settings into substructs of _settings in a way that they are logically grouped.

(svn r13225) -Fix (r13041): Missing calls to FindWindowPlacementAndResize() from lots
of windows causing 'two stage' opening effect.

(svn r11579) -Revert(r11578): some cases of key propagation are not handled correctly.
A better solution will be deviced, but not now. Let's not cause a ton of bug reports

(svn r11578) -Codechange: Introduce the window default flag WDF_TEXTENTRY which specifies that the window holding it is actually one that enables an edit box.
Use this flag when dispatching a key event instead of using some hard coded window IDs.
This should ease a little bit the creation of new edit aware windows.

(svn r11374) -Codechange: Give meaning to the magical number that specifies the color of the text in a DrawString call.
Patch heavily based on BiBB's work (FS#1383)

(svn r10665) -Codechange: replace magic 15 with MAX_TILE_HEIGHT (bilbo)
-Codechange: replace magic 13 with MAX_SNOWLINE_HEIGHT (bilbo)
-Codechange: assure _map_height_bits is always of correct size (Rubidium)
