refactor much more of the script into functions. Later we can add
parallel test running to the tool. But better structure may help
even if someone decides to translate this into another scripting
language instead.

* Scripts/run-webkit-tests: Break more pieces of the script into
seprate functions. Added readSkippedFiles, findTestsToRun, and
printResults functions. Removed custom code to skip results.html
and instead just put it into the ignoredFiles hash. Fixed some
indentation. Sorted function declarations, global variables,
and options at the top of the file alphabetically so they're not
in a semi-random order.
