Fixes to EditStyle dlg box:

- Better tab clef names than "Tab1" Tab2", i.e.: "Standard TAB clef" and "Serif TAB clef"
- Corrected dlg tab order
- Added all buddy links.
Restore original dlg height
Removing default usages of the PERC2 and TAB2 clefs.

- PERC2 is no longer supported and always rendered as PERC; using it as default, as in importxml.cpp is obsolete.
- TAB is the default tab clef, and TAB2 only remains as a stylistic variant.
