t-sql for exyus all checked in

[mca]

i was able to power through the rest of t-sql support for the
XmlSqlResource class in exyus this evening. full support for
PUT(create/update) w/ ETags. it went easier than i thought it would.
the ETag code from the XmlFileResource was very easy to drop in and
tweak. nice to see that HTTP calls (HEAD w/ ETag) work like a champ
for any representation [grin]!

i still need to beat this up for a bit and clean out the cobwebs and
such. but i should have a solid release within a day or so. i had fun
whipping up transforms for text/xml and text/html representations for
a simple resource. i find myself starting to think pretty easily in
mime-types and transformations - at least for HTML and XML types. i
still have to do some work to get my head to easily think in JSON,
tho.

anyway, fun evening and it's all booked into source control - sweet!
