RPM SPEC Changes

- Bumped version
- Added buildrequires
- Added CentOS 6 specific if statements for:
    - Autoconf is 2.63 (not the required 2.64)
    - Binary is in /usr/sbin instead of /usr/bin (not sure if this is CentOS specific)
- Added man files to installed files
- Added a bit of a changelog (dates in the master/CHANGELOG seemed to flip randomly between YYYY-MM-DD and YYYY-DD-MM)

If someone can test with Fedora/any other RPM distro to make sure it works, I can confirm it works in CentOS 6.x (both build and run)
