[BUGFIX] Visual regressions and unifications in Backend

Unifies tables in documentation, web>info page info + language,
scheduler edit and typoscript object browser.

Also due to the introduction of Bootstrap and refactoring of
t3skin/CSS several views broke. Fixes these.

Removes the FontAwesome save button for now.
