Release 0.1.5

- After seeing that wget was not actually getting the source how it was supposed to I made a few changes. So instead of using wget to retrieve commits and the kernel versions I am using git ls-remote it is way better.
- Date now is using the build date instead of the date of the commit
- Instead of looking for the rpmbuild folder in home which is the default directory I am retrieving the information from the %{_topdir} variable. This way if somebody has setup the rmpbuild directory to another location the script will still be able to function properly.
