[TYPO3-ttnews] tt_news 3.0 news caching update

[Rupert Germann]

hi,

latest news from svn (mostly caching related):

in short:
now you can choose in the extensionmanager which caching engine tt_news
should use.

Changelog:
* connected the internal caching from tt_news to the TYPO3 caching framework
(requires at least TYPO3 4.3). By default it's configured to use the DB
backend but of course it will work with all other available caching
backEnds too (tested with memcached, APC, filecache and DB)

* Added a switch to the extmanager config where one can choose the "caching
Engine" (options: internal, cachingFramework). If the caching framework is
not available (TYPO3 < v4.3) tt_news automatically falls back to the
internal caching. 
 
* Moved the caching related functions to their own classfile:
lib/class.tx_ttnews_cache.php

* changed the "lifetime" handling of cache entries to use the same system as
the caching framework.

* changed the fieldnames of table tt_news_cache to make it work with the
caching framework and the internal caching.

* fixed bug #11236:  Wrong param passed to getSubCategoriesForMenu 
* fix: moved the call to function initCategories() inside the $codes loop
because initCategories() requires $this->theCode to be set.
