- script can now handle other formats than just .tar.bz2 (automatic detection tested with .tar.xz)

- Information text about GNU Arm Embedded Toolchain download location updated.
- Fix: Installation path and link path would not interprete '~' as alias for ${HOME} correctly.

Bootloader versions of all modules are updated to 1.1.5.

- setuplib.sh: readUserInput function now allows to optionally use the escape key to abort input.
               The function has been renamed to readUserSelection to force incompatibility.
- All other scripts have been updated accordingly.
- It is now possible to use user input 'q' in interactive menus.
- All script parameters '-q' (short for --quit) have been removed.

- the version of a new installation is now printed even if this is the first installation (PATH variable not updated yet)
- fixed the recent fix for when .bashrc is no file but a link (not all cases were fixed)
