Feature: Possibility to select drop-down by index, value, and visible text.

[sankouski-dzmitry]

Currently, htmlelements have the only way to fill Select elements in Form element: by value.

I suggest to add possibility to specify select fill strategy (index, value, text)

It could be done, for example with parsing value:
if value begins with 'index=' than Select::selectByIndex method will be used
if value begins with 'text=' than Select::selectByVisibleText method will be used
etc..
