Here comes a more enhanced version which also is able to check for a 
specific version number of an installed extension. And even other 
attributes of an extension could be checked, if this information is 
provided.


ext
Syntax:
[ext=extensionkey:parameter = value1, >value2, =value3, <value4, ...]

Comparison:
The values are compared with the attributes of the extension key .
paramters:
isLoaded, title, author, author_email, author_company, version, 
CGLcompliance, CGLcompliance_note
Examples:

	[ext=tt_news:active = 1]
or
	[ext=tt_news:version > 1.2.3]


This patch contains modifications and bug fixes to the extenson 
patch10011 version 0.1.0. 'active' is used instead of 'isLoaded'. See 
Robert Lemke's comment.
Some methods have been borrowed from the EM because they are needed as a 
library. I could remove the duplicate code later in a separate patch.

Regards,

Franz
