Add space in Recent Files List to improve readability
Merge remote-tracking branch 'freeplane/master'
Last Opened Maps list :
- remove ":" after "Mindmap" label
- add space between label and MindMap path.

Benefits : more easy to read for user (space added), less caracters (":"
removed), multi-linguale support (for instance in french one should
write : "map : c:\..." and in english "map: c:\...")
