Credis in /lib to maintain compatibility with Cm_Redis_Cache_Backend?

[riconeitzel]

If you install both you'll end up with two Credis folders:
./lib/Credis
./app/code/local/Credis

Shouldn't it be just one? (./lib)

Magento core includes a copy at lib/Credis which is not updated as frequently and which the github module has no control over so putting another copy in app/code/local/ causes it to load the newest one instead of the one in lib/ without actually overwriting any core files.
