BrowserDetect directive

[leostera]

That way the following code can be used

section.ie(ng-browser-detect="ie<9")
  span.error This browser is not supported. Please use a decent browser.

It should support:

• browser name and version (e.g. chrome 27)
• browser name and version expression (e.g. chrome >25)
• browser family (e.g. webkit)
• browser os (e.g. os x, windows, android)

And it should be able to define any of those separately or within an object:

section.ie(ng-browser-detect=" { name: 'chrome', version: '>25', os: 'os x' }")
  span.error I'm sorry but we don't support Google Chrome 25 on Mac OS X
