Title: Remove &moduleclass_sfx from <input> and <button> elements

Removing the module class suffix from and elements in mod_search.

They're not needed for anything but it may well break layouts if a suffix is entered.
Also it's the only core module (I think) where it's applied to those elements. Normally it's only applied to the parent

where it makes sense as there is a specific module class.

This PR is based on a discussion in the JBS Google Group:
