logic: fixes all over the place

* fixed refreshing to send another ui refresh message after parsing
* keepContent field for MessageBase so that views won't update
* fixed searchmatching to only weigh uppercase letters next to lowercase ones
* fixed file not jumping back to snippets when activating edge
* clicking into empty space deselects active edge
* clear file manager files on every fetch
* added db transaction for file clearing
* use zooming instead of changing font size
