Fix FileActions merging override

use icon-confirm instead of text for accepting remote share, works better with translations

Return and use isPreviewAvailable for share previews

When merging FileActions, the register() functio needs to correctly
override the previously merged action handler without affecting the
original one.

All subclasses must also properly return the ajax call object.

Since the mime type is known, now isPreviewAvailable is returned as well
and used by the JS side to properly render mime icon and previews.
