Made default double click behavior open file:line

This commit flips the normal doble click behavior with the "⌥ + double click" behavior.

The reason for this is that the ⌥ key can interfere with the AppleScript in `xedReplacement.sh`, leading to some of the issues discussed at https://github.com/fpillet/NSLogger/issues/30

Also, added ⌘+F shortcut for faster access to filtering.
