floobits doesn't notice new files

[knupfer]

floobits notices only new files when you use the add-to-workspace function or when you leave and join the workspace.
This is quite dangerous, because the new file will be noticed for example a day later which exposes the user to the quite aggressive merging.

Proposed solutions:
• check upon leaving a workspace if there are untracked files and
• add them automatically, because floobits doesn't allow async stuff
• ask whether the user likes to put them in .floobitsignore
• add a hook to saving files which checks whether it is in a floobit-workspace and add it
