added submit button id, text field value support and resetForm

Submit button now supports html id for targeted event handling.

    {{submit_button "Submit" id="btnInsert" class="btn-primary btn-lg btn-block"}}

This is handled in helpers.js see processId function.

Text field now supports value including run time values like helpers,  methods, reactive values, etc...

    {{text_field 'name' value="business name" label="Business Name" placeholder="Enter business name" value='Krusty Burger'}}

OR

    {{text_field 'name' value="business name" label="Business Name" placeholder="Enter business name" value=getBusinessName}}

SimpleForm now has a resetForm method.
