First pass at rewriting the Learning wizard.
Add some ways for users to make the learning process faster.
Fix non-resizing UI
Fix bad xml and incorrect start page
Start adding titles to all of the controls
Rename ALL the controls!
Populate the combo box so completion works.
unneeded hack
cleanups
Slightly clearer text
Address some midi learn notes
Fix retry button not working
Fix some control menu items
Make it even more clear that you can click anywhere in Mixxx.  Really, really clear.
Because even I never knew you could do that.  Frankly I think we need a picture of
a mouse cursor over the Mixxx ui.  anyway.
make html text more translatable
Fix some of the midi learn grammar in anticipation of substring search
Don't allow user insertions of the combo box :)
Mark html as no-translate
Add a cancel button to the Learn page.
Try to make the "not quite right" section not overflow.
Fix typo, second BPM menu should be Sync
Manage disable and focus of Learn button.
Make sure to say "ready to learn" when a control is chosen.
Refuse to try to learn controls that are deprecated.
