(svn r14242) -Fix: removed some possible infinite loop in version determination (again).

(svn r14241) -Fix [Debian]: Remove an extra ~ in the Debian version.

(svn r14240) -Doc: add a few pointers/"howto"-ish lines to the obg format documentation about what it does and does not do and how you should fill the data.

(svn r14239) -Fix [FS#2267]: The engine-purchase-list-sorter doubled running-cost and halfed capacity of double-headed engines.

(svn r14238) -Change [Debian]: Update Debian packaging files to the latest official Debian version.
- Packaging files are now identical to those of the official 0.6.2-1 (or,
r11138 in the collab-maint subversion repository), with the following
exceptions:
- Desktop files are removed, since openttd trunk installs them already.
- Changes regarding package names from r14237 are preserved.
- Topmost changelog entry with version 0.7~svn-1 is added.

(svn r14237) -Feature [Debian]: Allow the Debian packaging to change the package name of the resulting package.
- The name can be changed at build time, by changing the package name in debian/changelog.
- This will allow packages like openttd-svn or openttd-cargodest packages to be built.

(svn r14235) -Fix (r14234): compilation with MSVC was broken

(svn r14234) -Fix: feeder share was computed wrong when splitting cargo packet

(svn r14233) -Feature/Fix [FS#2172]: save the palette of the loaded NewGRFs in the savegame, so joining with a server using Windows palette will make a client with the DOS palette do palette conversion and (thus) not cause a desync due to the different palettes disabling different NewGRFs.

(svn r14232) -Codechange: use builtin for byte swapping for gcc >= 4.3
