Revisions for ulaform/lib/api.php

* Rename $ulaform to $ulaform_driver to avoid global variable conflict
* Move getFieldsList out of the driver and into the application class because URL construction does not belong in the driver

API docs

- Add api method to display a form (not need to create a separete http request to integrate in existing horde app)
- Make getForm return and error if form does not exist so we handle a sql error or form existence check in the same check.
- Do not user select *
- @define -> define

apparently i committed only the changelog?

Block APIs are now exposed globally by the Horde API.
Some blocks probably have yet to be fixed because we don't include
lib/base.php anymore.

Blocks are no longer defined by the applications' api.php files or
registry.php. Instead we scan all application/lib/Block directories for blocks
once per session now.

use new stringArray type instead of 'array.' The argument types look sane,
but some of the return types aren't quite right yet, mostly the block API
calls, which return Horde_Block objects.

Happy new year everyone.

PHP 5 fixes.

Another chunk of Blocks work:

- move all parameter listing into block getParams() methods
- remove unused parameters from the _blocks() arrays
- make sure that all apps that have getParams() blocks have
a defineBlock() method.

Still need to move parameters for the Horde (applet) blocks, and
clean up registry.php.

- Block::isEditable() isn't used and isn't needed
- Make classnames consistent in all applications
- Make block instantiation consistent in most applications.

Various fixes to prevent errors in the portal view when things aren't configured, etc.
