Enhancement: Add "Search selected text" option to the mouse context menu

[TriVoxel]

I noticed there is a feature to "Search selected text" which can be done with Ctrl+S, or optionaly with double-click in Preferences. I think if you added the option to the mouse right click context menu, it would make it a lot more accessible to the average user.

Need to look into if this is actually possible. Will implement if so :)

Maybe it would be easier to implement a command line argument, e.g.: -s, to search the selected word as soon as the program opens. In this way, a user could create a keyboard shortcut like wordbook -s to quickly search for the currently selected text.
