User defined languages

[natecorkish]

This pull request gives the end user the choice to choose their own languages to show css completions. For example, say someone wants to add autocompletions to a file called .johndoe they can add it to their settings like so:

    "html-css-class-completion.enabledHTMLLanguages": [
        "html",
        "django-html",
        "razor",
        "php",
        "blade",
        "vue",
        "twig",
        "markdown",
        "erb",
        "handlebars",
        "ejs",
        "svelte",
       "johndoe"
    ],

This will save time for all the individual edge cases we have with people wanting support for different file types.

@zignd bump. This would be nice to have, love this extension but I can't use it with svelte!

That's an amazing contribution @natecorkish! I'll test it and release it as soon as I can!

By the way, thanks for the mention @a6h-s, I totally missed the initial notification for this PR.

@natecorkish I was trying it out locally and it's working perfectly, but I did notice that when the user updates the configurations, the changes are not taking place. I believe it's likely because it's necessary to listen to those changes here in the code and then properly update the context.subscriptions.

Do you think you could add this detail as well? Otherwise I can still do it on my side once I merge it, no problem at all. Also, thanks for taking your time to implement it :)

Merged to master manually 524b4f0. I'm still going to write some documentation tomorrow to explain this feature before the release and I'm also considering writing some tests as well.
