Feature: enabling continuous button press

[shaolin405mi16]

Hi, this patch includes one bugfix (when returning negative value), and also a huge feature addition.

This enables "autorepeat" feature: numbers continuously up/down while pressing increment/decrement buttons. So you don't have to click/tap up/down buttons number of times anymore, in order to increase/decrease numbers plenty. To accomplish this, I changed the way negative sign and current value(s) are displayed (from ng-bind to direct DOM manipulation).

Also, since touchscreen devices (such as smartphones and tablets) cannot handle mousedown and mouseup events, I added ng-touchstart and ng-touchend directives. If you add ngTouch ( https://github.com/nglar/ngTouch ) module, autorepeat feature will be enabled on touchscreen devices as well. Without ngTouch module, these directives are simply ignored.

Hope you'll like this.

further commits to make usable both on PC browsers and touchscreen devices. Introduced useNgTouch option (defaults to false). Probably nice as: useNgTouch: ionic.Platform.isWebView() ? true : false.

• if useNgTouch is set to false, mouseup / mousedown events are detected.
  • on PC browsers: auto-repeat is enabled
  • on touchscreen devices: auto-repeat is disabled
• if useNgTouch is set to true AND ngTouch module installed, touchstart / touchend events are detected.
  • on PC browsers: don't increment/decrement at all (sigh)
  • on touchscreen devices: auto-repeat is enabled

Also, introduced a 600ms delay before autorepeat for better usability.

Is this going to get merged to master?

@mikepc For the time being, use my forked master instead. Will get this pull request without a conflict later.

Just needs to be cleaned up and I can merge.
