Bug 739659 - Composer has two different context menus

Show the Evolution's context menu instead of WebKit's one when the Menu
key is pressed.
EHTMLEditorView - Don't crash when the paste button is pressed and the view is not focused
EHTMLEditor - Refactor the core editor actions (indent, unindent, ..) to their own group
EMsgComposer - Make the undo and redo work in Subject and Reply-To input widgets
EHTMLEditorActions - Process some of the EHTMLEditor actions just when is has focus
