Configure octave syntax highlight support as MATLAB (.m) files.

[evandrocoan]

Octave and MATLAB files use the same syntax highlight, but the editor does not know that.
Could we teach him?

Sorry, i forgot to say that the MATLAB syntax highlight is already supported.
Then what remains is just set (.m) files to use the MATLAB highlight.

[evandrocoan]

And i too noticed that, the (.m) files are setted to Objective-C syntax highlight.
So, what happens is that Objective-C, MATLAB and Octave use the same file extension (.m), but only MATLAB and Octave share the same syntax highlight.
In the end, remains to add a feature to the editor to associate/exchange the default syntax highlight to a selected file extension (like our .m files).

Normally that would require only adding it to https://github.com/ajaxorg/ace/blob/master/lib/ace/ext/modelist.js#L117, but m extension is already taken by ObjectiveC mode, so we need some way to detect language based on file contents. #849
But where do you Ace? Normally IDEs have a way to switch the mode manually.

Thanks nightwing, I code at cloud9, it's supports that i change manually the syntax highlights, but its annouying.

[nightwing]

Ah, i see. It also needs a way to manually change default mode for all files, not just one.

[evandrocoan]

It's what i should say since the beginning.
Thanks nightwing.

Until the ui is added, you can run the following code snippet in the browser console.

var settingPlugin = apf.getPlugin("settings"); 
types = settingPlugin.getJson("user/ace/custom-types"); 
types["m"] = "matlab";
settingPlugin.setJson("user/ace/custom-types", types)

merging this issue into #849

Thank you, nightwing :)
