Fixes schema format issues
Remove submodule note and other volatile info from README

In addition to removing the stuff pertaining to downloading submodules I also removed the note about not downloading the zip. I've tested building via the snapshot myself and it works fine. Finally, I removed some information about compiling the bot so that it won't have to be changed as often in the future.
Add myself to README

This might make me seem like an ass, I know. But the more projects like this I appear in a more obvious place in the better for future endeavors. So just consider it helping poor ol' Lagg get a better career.

Schema.cs fix
Removes travis from README
BUGFIX: GenericInventory crashes if you attempt to load it twice
BUGFIX: Web commands throw exceptions rather than retrying (or returning false...)
BUGFIX: TradeSession.AcceptTradeWebCmd was still incorrectly returning false sometimes
Minor code cleanup
BUGFIX: Sometimes the "Are you AFK" message gets fired multiple times (or not at all, depending on the polling interval)
BUGFIX: Trade sometimes crashes if the user-handler doesn't do a Poll() immediately before calling Trade.Ready().  However, there is no reason they should have to remember to do that (even AdminUserHandler forgot it..)
Simple code cleanup
BUGFIX: SteamWeb.Request sometimes returning HTML instead of json response.

Also updated the useragent because reasons.
BUGFIX: Removing an item by defindex crashes if we have a non-TF2 (GenericInventory) item up for trade
BUGFIX: If the trade disconnects while the bot is polling, the program will crash in CheckTradeTimeout()
BUGFIX: By adding items from some games (such as Spiral Knights), user can consistently cause the bot to crash.  THIS IS A BREAKING CHANGE :(
Also, unexpected side-fix:  Trade.GetItemFromPrivateBp() appears to have been incorrect.
