Add initial -rc support to the install.sh script. (#62)

* Add initial -rc support to install.sh script.

* Fix wording.

* Creating a RPM doesn't seem to create a package with the -rc name on it, so add it manually.

* Fix issues with patch applying when the source folder already exists.

* rpm-src is webscale.

* Turns out you can't use dashes in rpm-src, good to know.

* Final fixes.

* Re-use the .tar.gz file we downloaded if re-building.

* Make tar less verbose.

* oops

* linux59-rc: install.sh: Fix DEB naming in install process

* linux59-rc: install.sh: Use git instead of tar packages

Fix #58
