Manual talk:Running MediaWiki on Ubuntu

For a presentation I went through an install/config several times and touched up this page to match what I learned:
 * All references to VMware removed - unnecessary
 * Chatty reference to UK download site removed
 * Added note about how to find correct current version (and updated to reflect 1.9.3 is current)
 * Reorganized headings to make more sense

I think the whole area at the end regarding making an offline copy of MediaWiki help is unnecessary and confusing. I put it into an entirely separate heading, but I'm leaning towards deleting it.
