Extended grml2iso to add default bootoptions and copy external files to

generated iso.

Added -b option for specifying default boot options.
Added -c option for copying the contents of the specified directory to the
generated iso image.

Added -f flag to grml2iso forcing overwrite of existing iso image.

Adjusted documentation of grml2iso.
