Make it easier to define dictionary entries with control keys

[km-pg]

Summary

I would like it to be easier to build dictionary entries that involve control keys. (like Ctrl, Alt, Shift, etc) Right now you have to type the names of the keys into Plover. What if you could just press them?

Reproducing

Open the add translation window. Click in the translation text box. Press a key combination. (for example Ctrl+Shift+O) Notice that nothing shows up in the translation text box. Would be nice if {#Control_L(Shift_L(o))} (or whatever the equivalent was) showed up.

This is not that useful for people not using a NKRO-keyboard for Plover (which is likely what you use when you get faster anyway), and you can define dictionary entries for {#, control(, shift(, etc. to speed up the entry.

With PyQt, it isn't very hard to implement, and can be made into a plugin. Just use a QKeySequenceEdit.
