show new row when adding to lookup

This renders the newly created row and adds it dynamically to the
existing table.

Schema existence is now checked in Search

this avoids instantiating the schema twice

renamed SchemaData and SchemaLookupData

This is to reflect that they no longer inherit from Schema

refactor SchemaData into AccessTable with factory

classes. Both now inherit from AccessTable which provides common methods

refactor SchemaData into AccessTable with factory

first part of the refactoring for the SchemaData and SchemaLookupData
classes. Both now inherit from AccessTable which provides common methods
and two factory methods to automatically create the correct class
depending on the schema.

Both classes no longer inherit from Schema. Instead they contain a
Schema as a member variable. This makes it possible to initialize them
with an existing schema (which is required for the factory methods).

The flow is now like this:

1: init a schema (read info from the database)
2: look at the schema to figure out if it's a lookup or not
3: initialize the right Data object with the schema

first go at the lookup table editor

All functionality is added via JavaScript after an initial AJAX call.
This call can be used to check permissions later (without the need to
invalidate caches)

changed SchemaData to have options for output control

instead of having a whole bunch of paramters to the output functions.
Introduces rawValue cleaning as a new option.

Utilize StructException's translation handling

Use existing exception instead of new msg handling

Localize error message

Show error-message if schema does not exist

That way it is more clear where the problem lies and what to do.

SPR-501

Ensure that struct output is only rendered once

SPR-491

Use DokuWiki new autoloader for class files

No longer do we need to register our own autoloader. Namespace had to be
vendor prefixed.
