Form reset should reset text fields to initial state

[halvardos]

Calling .reset() on a form element, or using a reset button should reset text fields to initial state.

Codepen

At the moment the text field remains dirty (and invalid even if not required) after a reset requiring the developer to add a call to MaterialTextfield.checkDirty(); but this does not remove invalid state, so we have to manually call MaterialTextfield.change(); to both remove dirty and invalid state.

I see there are some issues that have been opened earlier about this but they have been closed without solving this issue. IMO this is not working as one would expect and should be remedied.

We'll work on this with the V2 make-over. 1.x is as-is unless a community member would like to contribute a patch to address this.

Thanks for the report.
