2.5 - Start of filebrowser.

- basic drawing of list and thumbnail view (switchable through 'favourits' icon in header)
- selection of files and directories (bookmarks) works with the RMB (right mouse button)
- load operator for files still unstable (no check for correct file type) and incomplete. (WM_operator_free missing)
immediate TODOS:
- fix load file operator
- finish drawing of buttons in header
- drawing of detailed list with all file info.
- finish selection and execute operators (LMB and MMB execute)
later todos:
- parent dir
- keymap for all the shortcuts
- append/link and databrowse
- ...
