new startcenter UI

Hi  Krisztian, all,


With commit https://gerrit.libreoffice.org/5319
(I think) the startcenter UI has been changed drastically.

I have no opinion whether this UI looks and works better than the old one, but :
-recently used documents are shown in tiles and longer document names are abbreviated, making it 
impossible to distinguish between documents with identical beginning of the name (which is quite 
common, e.g. a project number, followed by more specific information in the name). Could the 
complete file name be shown as a hint or something?
-For a longish list of recent documents, tile presentation is far from efficient. An optional 
simple list would be a useful alternative presentation.

(My master branch was pulled yesterday).

I hope my feed back makes sense.
