add support for scaling/sizing jtab rendering

[tardate]

currently diagrams are drawn in only one size. Add ability to support at least 3 sizes.
Side goal: squeeze 4 bars of tab to a line

You can use CSS to "zoom" in to make the chords effectively larger. Something like "zoom:2; -moz-transform: scale(2);" on the jtab div.

I currently use some edits in the source code:

var incFactor = 2.5;
Raphael.fn.string_spacing = 16 * incFactor;
Raphael.fn.strings_drawn = 6;
Raphael.fn.fret_spacing = 16 * incFactor;
Raphael.fn.frets_drawn = 4;
Raphael.fn.note_radius = 7 * incFactor;

Then I can change and store the values in web storage and manipulaet as needed.

Does jtab supports angular js?? I observed the thing that when trigger takes place it changes the URL followed by tab Id.But the doubt is that when I used with angular js it was not working.It just display a blank page....

And one more thing the tab trigger should change the content of the div not the entire page like what data toggle happens...
