Subject: [PATCH] file selection: match anywhere in the filename, not just at
 the start

Previously, only the start of the filename was matched. Now, the entire
file name is searched (case insensitive), e.g. if you have 3 files named
"foobar", "foobaz", "foolol", you can simply start typing "lol" and the
last file will be selected automatically.

This applies to both, list view and icon view.

Closes #2660.
