Fixed IE scrollbar issues for most if not all components
Fixed by defining font-size:0 and line-height:normal for all v-scrollable elements. A font-size is defined using $font-size for all themes and this is reset in v-widget. Similarly for $line-height.
Should fix at least #9004, #9552, #9572

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.
