I tested a few strings and found the function to be case sensitive.

You have to stick to these strings (whatever "pl" may be):

dev < alpha = a < beta = b < RC < pl

So the only thing is, we must use this capitalization.

But I don't recommend testing of alpha, etc for public production 
extensions. int_from_ver() should be good enough for most cases, but it 
won't hurt to be version_compare() compatible.

For simpler checks we could also introduce TYPO3_version_major and 
TYPO3_version_minor (currently "4" and "0")
