[Click] "require(library FOO)" added to Click syntax

[Eddie Kohler]

Hey,

File inclusion, a frequently-requested feature, has been added to the Click 
configuration language syntax.  Thanks very much to Christian Kreibich for his 
initial patch.

It works like this: Put frequently-used compound elements and such into a 
common library file, such as library.click:

======library.click=======
elementclass Whatever { ... };

Store this file with your other Click configurations, or put it in CLICKPATH, 
in the "conf/" directory.

Then in your main Click configuration file just say:

======main.click===========
require(library library.click);
w :: Whatever;

Let us know if you have problems.
