Description

When creating runtime styles, the styler.js module is improperly escaping certain escape sequences, most notably line terminators. The following line in a TSS file: 
text: 'this is a \nlinebreak'
is actually rendering the line break in the generated code, instead of preserving the given text string. The line terminators that should specifically be handled are listed here: http://es5.github.io/#x7.3

    commit: https://github.com/appcelerator/alloy/commit/1f0e84a68f8e5b56a464b6d968f6965257e0b358 Functional test should be performed on the 1_2_X branch: 
       sudo npm install -g git://github.com/appcelerator/alloy.git#1_2_X
    And here are the steps:

    Create a default alloy app

    Set the index.xml like this:

       <Alloy>
   	<Window class="container">
   		<Label id="label" onClick="doClick"/>
   	</Window>
   </Alloy>

    Set the index.tss like this:

       ".container": {
   	backgroundColor:"white"
   }
   
   "Label": {
   	width: Ti.UI.SIZE,
   	height: Ti.UI.SIZE,
   	color: "#000",
   	text: "I have a \ntab"
   }

    Run the app

    Ensure that the generated "Resources/alloy/styles/index.js" file has no rendered line breaks in it.

    Package the app for Android. Ensure that is executes successfully.

    Another confirmation that this was resolved is in the duplicate ALOY-790

    Tested the above code with: Appcelerator Studio, build: 3.1.2.201308091728 Titanum SDK, build:3.1.3.v20130816184556 Alloy: 1.2.1-cr CLI: 3.1.2 Device: Galaxy Note2 Android version: 4.1.2 Followed test steps successfully.

    However, now when I use a line break into a view.xml file (example below) the line break code is not interpreted anymore and considered/showed as part of the main string. (Tested on iPhone Simulator)

    Turn out that using this coding way (instead of the one above), it works:
