[TxMt] Version control menu tweak

[Joshua Keroes]

When using version control, my commits outnumber my adds by an order
of magnitude or two. That being the case, why give "Add to repository"
top billing on these menus?

I've reordered the version control menus  on my system roughly in
order of usage. Huffman would be proud - they all start with "Commit"
now. :-)

e.g.

Commit
Diff with newest (HEAD)
Diff with previous revision (PREV)
Diff with working copy (BASE)
Diff with revision...
---
Log
---
Add to repository
Check out revision
---
(everything else)
