New value & set-value! core functions

[rm-hull]

value & set-value are primarily used to get/set the values of form elements such as input, select and textarea; they act much the same way as other core functions: text / set-text! / html / set-html!

Also clarified readme docs on how to run tests.

All the test pass according to the generated html/js, but I see the following on the command line:

$ lein cljsbuild test

Your value and set-value! look fine, but the readme change is a bit misleading. You only need phantomjs if you want to run lein cljsbuild test. Alternatively, you can run lein cljsbuild auto test to compile, and load resources/dommy-tests.html in a browser. If you fix the readme bit I'll gladly merge.
