Lowest BIN related fixes & optimizations (#101)

* Lowest BIN related fixes & optimizations

- Fix double-call of updateLowestBin due to a race condition where lastLowestBinUpdate is not updated by the async thread until after the following tick.
- Change the parsing of item prices to avoid using getAsInt on a decimal string that throws two exceptions per value parsed. I replaced it with the code that getAsInt ends up falling back to.
- Delete corrupted prices_*.gz file so that it can be re-downloaded.
- Make the Bazaar update retry after 60 seconds instead of 5 minutes to be consistent with auction average data.

* Remove corrupt file deletion code to avoid conflict with other PR
