Use native WebDriver event triggering, rather than Syn ones

[aik099]

We have several problems due usage of Syn library for JavaScript event triggering. I propose to switch to WebDriver native event triggering capabilities instead of using Syn library.

During the change we need to carefully check, that when using native WebDriver calls all JavaScript events, that were triggered by Syn library are still triggered by WebDriver itself.

• #20

Already closed by now: #78

Note that many places using Syn have been switched to the native API in the latest version. the remaining usages of Syn are:

• focus()
• blur()
• keyPress, keyDown and keyUp
• the custom event triggering inside the dragTo implementation
