allows to override styles more easily via new class tc-chosen
----
updated all of storyview, theme, palette, language
» both in ControlPanel as well as PageControls
» removed "current ..." form switchers as it's redundant
» streamlined toolbar buttons in ControlPanel, especially less spacing
----
fixed dropdown hover colour override
if I wouldn't then it would go blank owed to default drop-down styles
----
polished styles
» chosen items now more emphasized while curspor not indicating a link
» removed underline when hovering, used highlighted border colours instead
----
use snippets languageswitcher for pagecontrols button, after all
----
wrap all switchers in tc-chooser
----
apply big font only to buttons, not reveals in pagecontrols
----
moved language switcher wrapper class to snippet
improved language switcher image alignment
----
make tiddler and ControlPanel view behave the same. add generic tc-check-list setting. add generic input type checklist, vertical alignment.
now using css rem to address drop-downs for pagecontrols
thanks @pmario
removed css artefacts in vanilla/base from before merging @pmario's PR
with comments being baked-in I don't think we want these in the code
css simplification for .tc-chosen and tc-chooser-item
