Fix twxs#69: correcting the dictionary keywords

[ruilvo]

Hey,

This pull request is my attempt at solving the issue #69 that I raised.

I mashed together the original dictionary file and the previous commit ones, and added a couple missing keywords, like some Qt-related stuff and the keyword YES that was missing for some reason, while NO was in there.

I had to update some of the required packages to make it build, not sure if you'll be okay with that. Either way, I have built the .vsix and I have it on the releases section on my repo if you wanna give it a try for yourself and see the differences.

I'm making this pull request upstream because I hope this can benefit everybody.

Thanks for your work!
