Revise installation instructions

From OpenFOAMWiki

Hi Dominik,

OK, the problem in AllMake.stage5 with swak4Foam is currently fixed by using the Mercurial repository. But it could also use the SVN repository... let me report this on the bug tracker... OK, updated the existing bug report, comment #518: Unable to build swak4Foam 0.2.4 in foam-extend-3.0

Regarding the latest wiki page iteration: given the past issue with the DMCA take down that occurred over a year ago, as well as issues that some users have with using Git and SVN from Sourceforge.net, I suggest that a wiki page (and respective link) is added for the available git mirrors. If you agree, I can take care of that.

Best regards, Bruno

I've added the mirror information and since the Arch Linux related page has been updated, I've rehashed the old idea of using sub-pages for system-specific instructions.
