[Rest2web-develop] Changed all references to value "tests" into value "checks"...

...including the main Validator method, and all code tests.

Also moved the "import socket, struct" line inside both the dottedQuadToNum
and numToDottedQuad functions, and added tests to both of them.

Speaking of the latter function, one of the tests allowed me catch a bug in
it. I've been using that code for *years* now, I'm still shocked. :-)

Repeat after me: doctest, unittest, whatever, but test! ;-)

When I was growing up, my parents used to say to me, "Tom, finish your
dinner - people in China are starving." But after sailing to the edges
of the flat world for a year, I am now telling my own daughters, "Girls,
finish your homework - people in China and India are starving for your
jobs." -- Thomas L. Friedman, New York Times, April 2005
