[TIMOB-3418] Custom Font support on Android

Needs to go on 1.6.2 as well.

(from [d06a815b13625e60d5f43f717420af9ab2308db6]) Support custom fonts loaded in assets/fonts. [#3418] https://github.com/appcelerator/titanium_mobile/commit/d06a815b13625e60d5f43f717420af9ab2308db6"> https://github.com/appcelerator/titanium_mobile/commit/d06a815b1362...

(from [89670092e070d0c67f04300becd3b18285b3753a]) Move the default font file location to Resources/fonts so as to take advantage of our built-in builder.py file delta/deletion/addition checking. [#3418] https://github.com/appcelerator/titanium_mobile/commit/89670092e070d0c67f04300becd3b18285b3753a"> https://github.com/appcelerator/titanium_mobile/commit/89670092e070...

To use this, put your custom (third-party) font files in Resources/fonts (or Resources/android/fonts if you prefer ... both will be handled). Then when setting the font property of the view (Label, TextField, etc.), set the fontFamily member to the base filename of the font file (i.e., the file name without the extension).

EXAMPLE (to be used for QE testing as well):

• Create a new project.

• Create the Resources/fonts folder in that project.

• Download and unzip the attached Chantelli-Antiqua.zip file, and copy Chantelli-Antiqua.ttf into your Resources/fonts folder.

• Use this as your app.js:

   Titanium.UI.setBackgroundColor('#000');
   var win = Titanium.UI.createWindow({  
       title:'Test',
       backgroundColor:'#000',
       exitOnClose: true,
       layout: 'vertical'
   });
   
   var lbl = Ti.UI.createLabel({
       text: "Now is the time for all good men to come to the aid of their country",
       font: {fontFamily: 'chantelli_antiqua', fontSize: '15dp'},
       height: 'auto',
       width: 'auto',
       top:10,
       backgroundColor: 'red',
       color: 'white'
   });
   win.add(lbl);
   
   var tf = Ti.UI.createTextField({
       hintText: "Type here",
       font: {fontFamily: 'Chantelli_antiqua', fontSize: '15dp'},
       height: 'auto', width: '100%',
       top: 10
   });
   win.add(tf);
   
   var ta = Ti.UI.createTextArea({
       hintText: "Type here, mein Freund",
       font: {fontFamily: 'Chantelli_antiqua', fontSize: '15dp'},
       height: '80dp', width: '100%', borderRadius: '5',
       top: 10
   });
   win.add(ta);
   
   var btn = Ti.UI.createButton({
       font: {fontFamily: 'Chantelli_antiqua', fontSize: '15dp'},
       title: 'I am a button',
       height: 'auto', width: 'auto',
       top: 10
   });
   win.add(btn);
   
   var btn2 = Ti.UI.createButton({
       font: {fontFamily: 'Chantelli_antiqua', fontSize: '15dp', fontWeight: 'bold'},
       title: 'I am also a button',
       height: 'auto', width: 'auto',
       top: 10
   });
   win.add(btn2);
   
   var btn3 = Ti.UI.createButton({
       font: {fontFamily: 'Chantelli_antiqua', fontSize: '25dp', fontWeight: 'bold'},
       title: 'Ah, but so am I a button',
       height: 'auto', width: 'auto',
       top: 10
   });
   win.add(btn3);
   
   win.open();
   

Notice in several places we're setting font: {fontFamily: 'Chantelli_antiqua' ... }. (Case doesn't matter.)

When you run it, you will (or should) notice that the font is not a standard font. See attached screenshot.png.
