Fixed clearing masked indicators on updated lines.

Make code folding optional

Some users might consider code folding a needless distraction.
Several editors offer the option to turn code folding off.

This commit adds the editor.fold option, which is a boolean.
true enables code folding (default)
false disables code folding
Disabled 'Fold' menu instead of removing when no folding is allowed (ref #169).
Added reporting of process id for a conflicting process.
Moved 'Sort' menu to 'Edit'.
Fixed sorting when the sorted fragment ends with a newline.
Added fold indication of a current block (ref #168).
Added an example of styling individual keywords.
Added creating (missing) folders when saving a file (fixes #171).
Added `editor.autoreload` to enable reload of updated files (ref #172).

Thanks for Tim Mensch for suggestion and implementation.
Added Chinese translation (thanks to Chow CheeWen; ref #70).
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).
