Heavily stripped down version of aspnet tests: twice as fast for some tests

Based on pdonald's aspnet tests, this is a heavily stripped down version
that pulls every trick in the book, to double the performance of CPU bound
tests. Perhaps this is not production worthy, but should provide a good
basis of comparison against microframeworks/microplatforms that barely do
anything.

See README.md for more info.
Get aspnet-stripped working with MySQL, PostgreSQL, MongoDB

Since @pdonald did all the work to get ASP.NET working against these other
databases, we should get this working in aspnet-stripped, so that we can
see how much stripping improved performance with these databases. This
ports @pdonald's related changes from aspnet to aspnet-stripped.

Because some of the URLs have the '&' character in them, I had to fix
framework_test.py to do proper quoting so that the '&' character would not
be interpreted by the shell.
Fix README.md not to say that this is only for SQL Server

This now works against other databases.
