converted all of the simple Owin extensions to F#
cleaned up spacing in constants
added ReadFormAsync; made type names semantic
I believe the Trim() call was in error
removing the C# ReadFormAsync
first pass at WriteAsync; F# doesn't allow overloads so I need to learn more about how this works
wip
renaming ParseForm for unit test
all WriteAsync overloads, but with distinct names
added WriteAsync with overloads, but I had to use a type in order to do so. For consistency, I moved all of the extensions to a type.
shortened the host type name for better readability
removed vestigial cs files
changing the namespace for constants
marking internals
reapplying Literal attribute
removing `inline`
making all arguments into tuples
moved parseform unit tests into fsharp proj
making parseForm internal, changing caps for consistency
added conditional compilation for unit tests
removing unnecessary indentation
replaced recursion in parseForm with for/do
added a test for the case when a key has no value 'key='
