Re-map XS-conflicting keyboard shortcuts.

[patridge]

Attempt to resolve issue #2.

Mac

• Browse recent documents => Ctrl+E (changed to eliminate conflict with "Find Next Selection")
• Go to Definition+ => Ctrl+D (changed to eliminate conflict with "Build All")

PC

• Browse recent documents => Ctrl+E (only changed to keep consistent letter with Mac)
• Go to Definition+ => Alt+D (wanted to make consistent letter with Mac, but had to use Alt instead of Ctrl to avoid conflict with "Breakpoints")
• Previous Member => Ctrl+Shift+Up (changed to eliminate conflict with "Scroll line up")
• Next Member => Ctrl+Shift+Down (changed to eliminate conflict with "Scroll line down")

Sadly, I didn't test my Windows shortcuts very well. I still need to work on the Previous/Next Member since everything with Up/Down seems to conflict with something else.

I'm also planning to add a section to the README with the defaults.

It doesn't look like Windows XS supports Meta tags. I resolved as many as I could, but Toggle Unit Tests is still broken and doesn't have any T-key variants available (Ctrl+T = Run Unit Tests; Alt+T = Tools menu; Ctrl+Alt+T = Run XSLT; Ctrl+Shift+T = Go to Type…; Alt+Shift+T = Tasks).
