Filter files as you type

[mherrmann]

Say you have

• apple/
• banana.txt
• bananajuice.txt

When you type p, only apple/ should remain in the list of files and p should be highlighted. When you then press ESC, all files should be visible again. When you then type banana, only banana.txt and bananajuice.txt should be visible. Pressing Enter opens the currently selected file. Pressing Backspace deletes the last character from the current filter (eg. banana -> banan). If no filtering is currently taking place (eg. because the user pressed ESC), then Backspace should go up in the directory hierarchy.

This feature is closely related to #40 .
