Fix #7: Adopt PSR-2 coding standards

Implement filtering

Implement getUserCount capability

Add caching for users

Wordpress users are stored in an array to avoid querying the database
unnecessarily.

- wp2dw() function renamed to cacheUser()
- new cacheAllUsers() function

User Manager now displays non-filterable list of users

Displays a warning message if filters are used.

New wp2dw() protected method

Convert a Wordpress DB User row to DokuWiki user info array

User list referring to Wordpress admin

Implement getUsers capability (retrieveUsers() method).

For now, we just display an information message and an empty list.

Do not connect DB if we're already connected

Remove unnecessary variable assignment

Change properties and methods visibility

Use protected instead of private
