Code coloring broken for html file with Embedded JavaScript templates (EJS)

[dalcala]

Description:
Code coloring broken for html file with Embedded JavaScript templates (EJS). I got this file from the Adobe CSS FilterLab repo: https://github.com/adobe/cssfilterlab/blob/master/index.html

Repro using Brackets Sprint 25 on Win 7 and Mac 10.7.

Repro steps:

1. Get this file and open it in Brackets: https://github.com/adobe/cssfilterlab/blob/master/index.html

Actual results:
The code coloring is broken, starting with this tag: <%- css %>.

Expected results:
Code coloring is not broken. Works fine in Sublime Text 2.

Workaround:
None.

Looks like this works in the code mirror demo http://codemirror.net/mode/htmlembedded/. However, we would either need to

A. Swap htmlmixed for htmlembedded or
B. Require EJS files to have a .ejs extension.

I think B is safe for now and we might reconsider A in the future. Eventually users will have the option to override the mode via https://trello.com/c/FaoluhZ5.

Reviewed, low priority to @jasonsanjose.

I submitted pull request #4166 that implements solution B.

This should be fixed now. At the very least, this bug should be marked FBNC.

@dalcala or @jasonsanjose, when you get a moment, please confirm this fix and close this bug.

It doesn't fix the original bug as filed -- .html files will still get treated as regular HTML -- but that's just a FOL until changing the syntax mode per-file or per-extension is implemented. It's definitely fixed for the .ejs extension, I think we're good to close.
