Fix blocks demo keyboard handling, add new shortcut.

Browse Source 
The blocks demo was unintentionally intercepting ctrl/+ which was
introduced in FLTK 1.4.0 to change scaling for HiDPI screens. Now this
is separated: use ctrl/+/-/0 to change scaling, use '+' alone to change
the game level.

The new keyboard shortcut ALT+SHIFT+H allows users to reset their high
scores without editing the preferences file.

Other Improvements
- (add new items here)
- The blocks demo program got a new keyboard shortcut (ALT+SHIFT+H) to
reset the user's high score. It is now slower than before in higher
levels, hence you can expect higher scores (due to a bug fix in the
timer code). You can use the '+' key to increase the level at all times.
- Some methods of Fl_Tabs are now virtual and/or protected for easier
subclassing without code duplication (STR #3211 and others).
To be continued...
