WindowModules - add "s" to a few descriptions/remove Sys Tray Menu


To the main description for the WindowModules, which is currently "Send a sequence of commands...", it ought to be "Sends a sequence of commands..." to keep consistency.

Also, down in the list of commands that the reaction has, the Move and Resize descriptions should be "Moves" and "Resizes" at the beginning of their descriptions.

Lastly, in the table on the left of the screen that lists the events and reactions, System Tray Menu is listed.
