Made several changes for use with TPC-H implementation and col-stores DBs:
- New benchmark states for cold and hot query runs.
- Can run queries serially (run each query in sequential order on one terminal)
  exactly once (a `latency' run) or for a set amount of time (looping through
  the query list until the timer expires).
- Added support for MonetDB in TPC-C.
- Can re-run a test using the .raw output. Submits identical queries to the
  system at the same time; for repeatability of tests.
- Can specify `groupings' of query weights in config file. A shorthand to
  make config management a little easier.
Update CH-benCHmark to support dialects, MonetDB.
Implemented TPC-H, including support for MySQL, MonetDB, and Postgres.

Fixed integer overflow problem for AuctionMarkUtil.getUniqueElementId(). The UserIds are now down to 40bits and the ItemIds are 56bits. That leaves us 7bits to generate a random number for the offset. I forget why we used it this way but hopefully this will fix things. This commit goes out to Canadian transplant Ryan Johnson.
