packages case sensitivity

[Elan Ruusamäe]

seems github packages are case insensitive, perhaps we should limit 
similarily in pld to disallow creating packages that differ just 
character case?

https://github.com/pld-linux/KeePassX/commits/master/

only problem i see ahead is that if character case cames from package 
rename. for example i'd like to normalize this package name to be 
keepassx, not KeePassX
