(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.

-/* How the resize system works:
-    First, you need to add a WWT_RESIZEBOX to the widgets, and you need
-     to add the flag WDF_RESIZABLE to the window. Now the window is ready
-     to resize itself.
-    As you may have noticed, all widgets have a RESIZE_XXX in their line.
-     This lines controls how the widgets behave on resize. RESIZE_NONE means
-     it doesn't do anything. Any other option let's one of the borders
-     move with the changed width/height. So if a widget has
-     RESIZE_RIGHT, and the window is made 5 pixels wider by the user,
-     the right of the window will also be made 5 pixels wider.
-    Now, what if you want to clamp a widget to the bottom? Give it the flag
-     RESIZE_TB. This is RESIZE_TOP + RESIZE_BOTTOM. Now if the window gets
-     5 pixels bigger, both the top and bottom gets 5 bigger, so the whole
-     widgets moves downwards without resizing, and appears to be clamped
-     to the bottom. Nice aint it?
-   You should know one more thing about this system. Most windows can't
-    handle an increase of 1 pixel. So there is a step function, which
-    let the windowsize only be changed by X pixels. You configure this
-    after making the window, like this:
-      w->resize.step_height = 10;
-    Now the window will only change in height in steps of 10.
-   You can also give a minimum width and height. The default value is
-    the default height/width of the window itself. You can change this
-    AFTER window-creation, with:
-     w->resize.width or w->resize.height.
-   That was all.. good luck, and enjoy :) -- TrueLight */
