Several changes to make edit.php a generic edit form

edit.php:
- use ?table= parameter to decide what will be edited
- generate (and validate) Handler classname based on ?table=
- read handler-specific configuration from $handler->webformConfig()
  and use it at various places
- add option to run $handler->init() early. Useful for $new in case
  of AliasdomainHandler which might fail if all domains are already
  aliased.
- always redirect to edit.php?table=$table after adding an item to
  ensure correct initialization for next item

templates/editform.tpl:
- add hidden field "table"
