Zen Coding interferes with Redo functionality

[HelderMagalhaes]

Zen Coding module is currently using Ctrl+Y shortcut key for its Evaluate Math Expression:

Unfortunately, this shortcut key interferes with Redo (a very basic and essential feature) in many English-speaking countries (and "imported" by many more such as Portugal).

Furthermore, as apparently the shortcut is not declared in a way Notepad++ understands (i.e., it doesn't display in the Settings --> Shortcut Mapper... dialog --> Plugin commands tab), made it quite a bit more tricky to find.

Suggestion: disable the shortcut by default, as it may be causing a lot of unexpected behavior.
