allow users to decode unicode escaped texts

Decoding strings like \uXXXX to normal Unicode text.

This looks great, though I would expect the command to actually be UnicodeUnescapeCommand - "escaping" unicode should convert the unicode symbols to \xxxx and unescaping should convert them back into text. What do you think of this change?

I tested this using the text \u0e4f\u032f\u0361\u0e4f and it had no effect. What is the expected behavior or test case for this plugin?

Oh, I see, it turns unicode characters into their escaped version – this is unfortunately a language-specific syntax (right now it's outputting in Python), but better than nothing.

It's very similar to this package: https://packagecontrol.io/packages/Unicode%20Escape

In the future it would be nice to detect the language and output the appropriate string, but like I said I think this works. Thanks!
