Steamodd

Changes this version:
- Fix for UGC URL in unit test from RJacksonm1
- Add support for new VDF list syntax from RJacksonm1
- Add _aggressive_ param to methods to force request fetching upon method call instead of lazy fetching
- Add level property to profile class

This is a minor release that includes a few fixes and cleanups.
- Fix by RJacksonM1 for steamodd's loc class throwing a LanguageUnsupportedError when it uses the environment language code and it's not supported (which would make it instantly throw despite the user not passing a custom language code)
- Feature by RJ for a stronger quality check in sim items if they exist (this is what is making CS GO items look right in optf2 despite being sim-loaded)
- Cleanup by actown for PEP-8 compliance

This is a bit more of keeping up with the ValveSoftware -ses. I updated the base API interface generator to allow overrides on the format and key parameters. There's not much practical use for format overrides unless you like breaking things or Valve adds a new json format but now that there are requests that associate an API key to an account it can sometimes be useful to override the default key. Attributes with weird effect types are also now handled without issue.

This changes a few things to keep up with ValveSoftware's current shenanigans

This is a maintenance release that works around a few consistency problems in the API.
- Catch top level socket read errors and reraise with HTTPError
- Revert removal of forced decode during deserialization, but also add compatibility code for pre-2.7 python
- Work around lack of tags object in dota 2 asset catalog (by RJacksonM1)

This is another **Steamodd Takes Valve's Hate So You Don't Have To!** (maintenance) release. It fixes a few issues arising from the latest update to the TF2 schema that adds strangifier recipies. For whatever reason Valve decided to add a brand new effect type to the attributes. As well as a new kill eater score type that is not consistent with any other naming scheme. Yay!
