Moar fixes (re ;ostly filtering mixed lib/data and regular files).

Make 'append/link' code handle data from several different sources at once.

Nothing really magic here, just grouping the imports by libfile/grouptype.
We could probably get better code (loop less on given list of 'files' to import)
but not sure it'd be worth it, this is not supposed to be a performance-critical point.

IME: Dynamic linking of IME libs

Moar fixes to sorting code and such.

minor corrections to last commit

IME: Initial Scons Support

Adds support for Scons flag WITH_BF_IME
**note:** dynamic linking of IME libs is still missing for Scons

Widget API: remove unused identifier member

also comment some of the code.

IME: Remove duplicate of GHOST_ImeWin32.h

Some flatmode fixes:

* Delete filelist when changing flat setting (so that we get immediate update when changing that setting).
* Disable flat when going up in tree (we ;ight actually want to do this everytime).

cleanup: picky edits

Ensure IME is _never_ used outside win32 platform
