Standard themes in SCSS form, updated CompileDefaultTheme (#9223)
Conversion performed for most themes trivial, just rename file and wrap
in a mixin. For chameleon compounds, also nesting used. In some cases,
related small files combined in a single SCSS file
Chameleon accordion and select contain fixes other than just a missing
semicolon.
Reduced many unnecessary element resize listeners and layout methods.
Refactored ComponentConnector style name handling so that it will now
only alter the style names and not completely override them on each
update.
