Keyboard shortcuts and context menus

[MarekKnapek]

Keyboard shortcuts (accelerators) are weird and broken. Tested only few, from modules tree view and modules list view. Ctrl+M (Highlight matching module) works well when pressed from context menu, but does not when pressed by keyboard shortcut. Show full paths (F9) does not work when pressed on keyboard.

Tree context menu Copy Path is always grey.

Tree context menu has two menu items with the same key shortcut (Alt+Enter).

Some context menu item have "Maj" as key modifier, I never seen such shortcut, maybe it should be "Shift"?

Select all module list view context menu is always gray.
