refs b125fab2ba

Introduce Form_Button, which can morph into <a class=btn>

fixes #11

After instantiation return object. Return object after setWidth.

Major change: require caller to specify name of inputs

no longer do we automatically determine an input-name; it meant a lot of
backend-changes (or forceName calls). This commit fixes all occurences
except for firewall_rules_edit
