Title: Additional Install Script

the install script provided gave me the following error:

cp: target `/home/andy/.local/share/gedit/styles/.' is not a directory

It seems that gedit sits in my file system differently than in yours.
I wrote an install script that works for my OS and gedit versions:
ubuntu 12.10
gedit 3.6.1
it is included in the directory as install_ubuntu.sh
