Cleanup: Remove obsolete (Make)EnumPropsT. (#10697)

This was used by the command system to help extract p1/p2 parameters, which no longer happens.

Fix #7307: Add WaterClass to MP_TREES, set when trees are on coast tiles (#7309)

This allows allows NewGRF object/industry placement rules to treat trees on coast tiles the same as regular bare coast.

(svn r12042) -Fix [FS#1676]: Reimplement how rivers and canals are stored in the map, allowing the sea/river/canal status to also be
stored for buoys, docks, locks and depots. All these are now allowed on rivers and removal of them will revert to the
original water type.

(svn r11276) -Codechange: be more consistent with naming of some accessors.
-Fix: make sure canals are never owned by water. Based on a patch by boekabart.

(svn r7759) -Merge: makefile rewrite. This merge features:
- A proper ./configure, so everything needs to be configured only once, not for every make.
- Usage of makedepend when available. This greatly reduces the time needed for generating the dependencies.
- A generator for all project files. There is a single file with sources, which is used to generate Makefiles and the project files for MSVC.
- Proper support for OSX universal binaries.
- Object files for non-MSVC compiles are also placed in separate directories, making is faster to switch between debug and release compiles and it does not touch the directory with the source files.
- Functionality to make a bundle of all needed files for for example a nightly or distribution of a binary with all needed GRFs and language files.

Note: as this merge moves almost all files, it is recommended to make a backup of your working copy before updating your working copy.
