Added MLB salaries for 6/14/2014
Moved scraper to its own package.
Fixed parameter being sent to find_all.

I was trying pass a regex into re.compile (oops).  Just removed the
re.compile() call.
Added check for current season in pitcher data.

If the pitcher, for some reason, doesn’t have data for the current
season then we just skip them.
Added flag to specify whether to skip BvP scraping.

Defaults to true (will skip BvP).
