tlmgr update --self on win32

Changes to tlmgr.pl:
- check_for_critical_updates returns a critical updates list instead of 0/1
- warning message moved to critical_updates_warning()
- some code clean-up, superfluous conditions removal
- filtering of critical packages from @todo _after_ dependency expansion
- support for tlmgr update --all --self --dry-run (recursive call to action_update)
- documentation updates

Changes to updater-w32:
- renamed updater-w32.bat to updater-w32 (cannot be executed accidentally)
- merged run-updater-w32 into updater-w32, arguments and options are passed
  through a subroutine appended at the end of updater-w32 at run-time
- support for debug mode
- reflect changes in tlmgr.bat and docs
