Patch and question about bash completion

[Konrad Scherer]

Hello all,

I found a bug in the import functionality when using the --available-as command 
line parameter. The function path_tail was not fully moved into utils. The 
attached patch fixes the version in utils and all import code now uses that 
function. The commit is also in my github repo 
https://github.com/kscherer/cobbler on branch wrs.

I also noticed that there is an incomplete bash completion file. The Makefile 
references a missing file called mkbash.py and the completion file references 
"cobbler-completion". I have often missed completion when using cobbler on the 
command line and was about to write my own. Any pointers to get this working 
would be appreciated.

Konrad
