Support for dark themes in default settings and restore defaults button

Browse Source 
All the colour configurations have been reviewed under an operating-system theme
dark theme.

Some hard-coded colours in QScintilla editors and Data Browser have been
replaced by queries of the system palette or reuse of our settings.

New settings for foreground and background colours for QScintilla editors
defaulting to system colours. This is mainly needed because if the user
saves colour settings for a dark theme and then he changes the system theme
back to a light theme, then the foreground colours are preserved while the
background would fall back to the system theme leading to an incompatible
combination. This also gives more freedom to the user in defining his own
colour combinations.

Since only the default colour settings adapt to the system theme, and once
settings are saved this can no longer happen, a 'Restore Defaults' button
is added so the default adapted colour settings can be restored. This is
also useful for restoring default behaviour when wanted.

Other fixes and improvements: waiting cursor while saving; check boxes in
SQL tab for bold, italic and underline when applicable; avoid translation
of hidden colour setting names used in code.

See related issue #1324.
