(svn r6381) -Cleanup: make the '/* */' comments that span multiple lines more uniform.
-Cleanup: whitespace alignment of a few tables.

(svn r5975) -Cleanup: use ORIGINAL_BASE_YEAR & ORIGINAL_MAX_YEAR where the functions really depend on the original date format.
-Cleanup: use DAYS_TILL_ORIGINAL_BASE_YEAR where the date variables are in the old date format and conversions are needed.
-Cleanup: replace one (forgotten) instance of uint16 with Date.

(svn r3181) -Bracing
-Indentation
-Whitespace
-DeMorgan's Law
-Test with NULL or 0 for non-booleans
-'\0' instead of 0 for chars

-Split single lines with multiple statements
-Avoid assignments in if

(svn r2685) -Codechange: Split the music/sound/video drivers into separate files and move them into subfolders.
This results in shorter and hopefully easier to maintain files.
Note: I had to change paths in #include statements of some unrelated files, because I added the ottd base directory to the include path (-I.)

(svn r2657) -Codechange: The available railtypes per player are now a bitmask, so
that railtypes do not be in ascending order of appearance. Allows easier
implementation or more railtypes

(svn r2428) - Feature: [newgrf] Implement shorter train vehicles (Therax), and the callback that goes with it.
- Codechange: Remove some magic numbers (PALETTE_CRASH)

(svn r1444) -Fix: fixed weight for double-head trains (and with that the acceleration)
(now maglev lvl4 can reach their top speed, and are faster than lvl3)
(Tnx to Darkvater :))
-Fix: Buy Vehicle GUI now shows HPs bigger than 32000 correctly

(svn r562) newgrf: Merge most of the road vehicle info to a single
road_vehicle_info table, like it already is for trains and ships. Needed
for GRF custom override support. (pasky)
