32 bit ID inaccuracies

[paralin]

The method I wrote into the latest version of the package for converting SteamID to 32 bit for Dota 2 might be incorrect. Here's what I'm currently using (kind of hacky)

@toSteamID32 = (id)->
     sids = (steamidconvert.convertToText id).split ":"
     id = parseInt sids[2]
     id*(2+parseInt(sids[1]))+1

This works with SteamTracks' backend. I think this solution might need to be integrated into this package.

When I was dealing with this issue during the first twitpocalypse, one way was to store them as strings. This is also why twitter api gives a id_str property along with the ids. May be we can try doing the same?
