webform_component table only allow types that are 16 char.

When creating custom webform components you can easily get hit by the database restriction of only allowing the type to be 16 chars long.

Is there any reason to not allow longer component mashine names which is easily required if you create a custom component in a module and name it [module name]_[description/name].

I'll be happy to write a patch that changes this from 16 to 32 or 64 if you would allow it to get it.
