[BZ#723129] Installer should support more languages than just English
Submitted by Keegan Witt

Currently the installer just supports English. The user should be able to choose a language to continue the installation in. Most of the labels we can just use the NSIS defaults. The only stuff we've overridden that would need work is the licenses file and the prompt for uninstalling when the software is already installed.
