Systemwide (non-persistent) memory

Background

for the TermTagger-plugin we need a simple system to log the availability of a TermTagger-server. Out of this requirement came the wish to have a system to store simple informations. In the meantime such a memory is needed at several places.

Goal

Store simple key/value-pairs in the database.

Details:

The Zend_Cache Backend ZfExtended_Cache_MySQLMemoryBackend was created. The cache length is limited to 4096 characters.

If additional functions like increment / decrement are needed, they must be implemented in a new Zend_Cache frontend. This is currently not needed, so not implemented.
