[dev] Block applets

[Chuck Hagenbuch]

Quoting Joe Wilson <joe.wilson at mindcandy.org>:

> Here is the patch I promised last week that generalizes the Block portal
> interface to allow the addition of new 'applets' without modifying the core
> Horde code (e.g. lib/api.php).  Simply add a new entry to
> $this->applets[{name}] in registry.php and place the code in
> lib/Block/{name}.php.

Committed, thanks! Please take a look at how my commit differed from your
original submission; there were a bunch of minor CODING_STANDARDS issues, along
with a few things that I cleaned up/did differently.
