Fixed debugger to accept filenames without '@'; thanks to Tim Mensch (closes #174).
Added package onAppFocus* events (ref #166; ref #172).
Updated `SaveAll` to allow saving (only) files with filenames (ref #172).

This is useful when `SaveAll` is called from a plugin and user interaction
(asking for a file name) is not desired.
Replaced package onEditorActivated event with onEditorFocus* events (ref #166).
Added search/completion in the local and remote console (closes #173).
Added erasing current line in Console (ref #173).
Merge branch 'master'
