Better handling of localization issues for s2gs

Throw a SC2ReaderLocalizationError when the translation table tells
us to use a sheet or key that doesn't exist for the localization
specified by the user.
Only throw LocalizationErrors in debug mode.

Make sure that we can struggle on in the face of any non-fatal errors
and recover things like the summary stats and gameplay graphs.
Possible fix for csv file issues on install.
Fix a warning on the MANIFEST file.
Return player and not the player index.
Fix camera location parsing.
Properly handle vikings.
Properly handle vikings.
Add full color support for summary players.
Add proper unit sorting criteria.
Fix camera location parsing.
Allow game state to support built-ins like tuples.
Add simple parse test utility.
Improve the sc2parse debugging script.
Adds CachedSC2Factories.

These factories perform basic caching of remote resources with minimal
configuration. There are currently three kinds:

* DictCachedSC2Factory - Caches results in memory with a dict. Uses an
    optional argument `cache_max_size` which dumbly limits the number
    of resources to cache in memory. Dict size is maintained by deleting
    the least active entry at insert time when full. Resource size can
    vary wildly at times; this factory does nothing to adjust for that.

* FileCachedSC2Factory - Cache results on disk in files. Requires your
    configuration with a pre-existing `cache_dir` for writing files.

* DoubleCachedSC2Factory - Uses both of the above caching layers to
    reduce IO time for commonly used resources. Order of operations:

	1. try to load from DictCache and return.
	2. try to load from FileCache, write to DictCache, and return.
	3. Load remote resource, write to both caches and return.

    Requires `cache_dir` and accepts an optional `cache_max_size` to
    limit the DictCache size.

These caching schemes can be enabled painlessly by calling:

 * sc2reader.useDictCache(cache_max_size=0, **SC2Factory_options)
 * sc2reader.useFileCache(cache_dir, **SC2Factory_options)
 * sc2reader.useDoubleCache(cache_dir, cache_max_size=0, **SC2Factory_options)

Thanks ggtracker for letting me push these utilties to the public repo.
