This removes a large array of deprecated functionality, regardless of how recently it was deprecated. The purpose of this commit is to clean out the standard libraries and compiler for the upcoming alpha release. Some notable compiler changes were to enable warnings for all now-deprecated command line arguments (previously the deprecated versions were silently accepted) as well as removing deriving(Zero) entirely (the trait was removed). The distribution no longer contains the libtime or libregex_macros crates. Both of these have been deprecated for some time and are available externally.
