Pull me, bro! (Lift 2.5-RC5)

Bumped: Lift 2.5-RC5, Scala 2.10.1, SBT 0.12.3

Added Scala 2.10.x language features to compile options so that it doesn't misbehave upon compilation.

Consolidated some tabs / newlines.

Removed "compile" Lift dependency in favor of "provided" for this fits better in the module principle - we do not download some exact Lift version but rather depend that *something* resembling 2.5 branch it will be provided for us.

Removed the logback and jcl bridging because the necessary logging dependencies will be injected through the provided Lift dependency.
