* DEV: Provide radix 10 argument to parseInt
* DEV: Provide radix 16 argument to parseInt
* DEV: Remove unnecessary parseInt calls
* Fix year formatting
parseInt was used here to convert decimals to ints
* Remove long-deprecated method
* FIX: Memory Leaks when decorating posts
Previously we'd keep creating mixins dynamically when decorating the
same class.
This code changes the API to recommend an `id` parameter for each
decorator which will avoid leaks. All plugins should be updated to
include this parameter, although if they don't in the meantime it'll
just mean a warning in the console (and a continued leak.)
