SSR & Boolean value compatibility

2.5.0 moves all .vue files to .js files and changes templates for render functions. It also fixes #8 where false boolean values were causing the labels to appear incorrectly.

Added validation messages

Validation messages have recently been added to Vue Formly. This release accommodates those changes by displaying the most recent validation error. Documentation will be added to the Vue Formly docs on how to add these validation messages.

Minor Updates with Breaking Changes

V2.0.1 just updates templateOptions to get rid of type and adds inputType on input fields. This is just for continuity.
