Feature: Update gruntfile

[edoparearyee]

This PR includes the following updates the build process:

• Disable qualified-headings options in lesslint task as bootstrap doesn't follow this rule.
• Allow style tag in htmllint for use in modules prototype pages.
• Split grunt watch tasks into smaller tasks so only the nessesary tasks are called when updating files.
• Move .csslintrc and .htmllint files into project root like jshintrc so easier to find.
• Lint html files in modules folder as well
• Remove grunt serverjs task as grunt serverall task does the same thing if only working on javascript
• Make grunt server task run all watch tasks just like with grunt serverall.
• Move all linting to it's own grunt task which is run in circle and travis as well.
• Minor html formatting

@edwardoparearyee so server and serverall now do the same thing, do we still need both?

[edoparearyee]

Yes they do, I was thinking the same but wasn't sure whether to keep it because we have gotten so used to using serverall. But yeah think we should drop serverall if your okay with it as well.

[jamesjwarren]

I'm good with dropping it, I like the simplification of just having one server task 👍

[edoparearyee]

I originally meant for grunt server as a way of refreshing the server and not running test incase it took ages to refresh due to hundreds of test but due to the way i've broken up the watch task it's not really possible anymore without running certain tasks unnecessarily. I'll remove it.

[edoparearyee]

@jamesjwarren should be fixed now

[jamesjwarren]

👍

[edoparearyee]

@jamesjwarren made one more change, updated the name of test commands to grunt test:unit:development, grunt test:unit:production and grunt test:e2e, let me know what you think

[jamesjwarren]

@edwardoparearyee yeh, thats cool 👍
