Made it a bit easier to add new fields and/or change their order
Replaced some unneccessary if-else-statements
Added font size and stroke width settings to ROI inspector
Fixed(?) a problem with too small figure text/comment boxes
Bugfix: Changing font size wasn't rendered on the fly
Fixed issue with invalid input for sizes (font size, width, etc.)
Removed wrong import statement
Remove ManagedRawFileStoreI in favor of callbacks

ManagedRawFileStoreI was not being used which meant that
closeCalled was never invoked and therefore the proxies
in `ManagedImportProcessI.uploaders` were never cleaned.
This led to `ObjectNotExistException` being thrown on a
second loading of `proc.getUploader(i)`. Rather than add
logic to create the correct subclass of RepoRawFileStoreI,
a callback interface has been added which can be used for
any implementation.
