(svn r3104) -Codechange: [refit] removed now obsolite code that the old autoreplace needed

(svn r3103) - Fix: [ 1339000 ] Fix: strgen and plural forms fatal error for untranslated strings. (glx). Also output the correct lines for these warnings, for missing strings the lines correspond with the ones in english.txt

(svn r3102) - Fix (regression): Newly added sprite had problems when newgrf's where loaded. Thanks Tron for explaining what the problem was and how it should be solved.

(svn r3101) -Codechange: added _new_vehicle_id
this var works like _new_train_id and the rest of that kind of vars, except it is set each time a vehicle is build, nomatter what type
this is a nice tool to code vehicle independent code, which in turn can reduce code duplication
Right now it's used in ReplaceVehicle() and CmdCloneVehicle()

(svn r3100) -Codechange [Clone vehicles] Major change to clone vehicles
removed duplicated code and added DoCommand, which used the define build commands added with autoreplace
This should not affect gameplay at all

(svn r3099) Copy&pasto in r3098

(svn r3098) static, const, uint -> TileIndex, indentation, bracing, unused return values, ... mostly related to the clone vehicle GUI

(svn r3097) - Fix (regression): unix has a trailing slash after the paths, windows does not, no idea why os2 has. Way to go consistency :s. So anyways, just strip trailing slash

(svn r3096) - Feature: 'HOME' icon to saveload dialogs that jumps to the default save/load directory based on the dialog (added icon to openttd.grf, introduced FIOS_TYPE_DIRECT that allows arbitrary directory jumping).
- Fix: on Win32 capitalize the drive-letter in the saveload dialog windows when it is first opened.

(svn r3093) -Fix: [autoreplace] fixed issue where the money limit message showed up in some cases when no replace was needed
