Allow to optionally limit the maximum number of text lines

Showing the whole filename unclipped seems to be a good default,
however for users with a lot of files that have extremely long names
this might get a problem especially in the icons-view.

- Allow to limit the maximum number of lines in the icons-view
- Allow to specify a maximum width in the compact-view

(No limit is required for the details-view, as the name is shortened
automatically to show other columns)
