Cleanup model/ct-commit and use every.

Cleanup model/ct-commit and use every.

-Get rid of url getter. There's no reason not to just
store the url as a regular property.
-Fix revision finder to not be blink specific.
-Don't split the whole message just to get the first line.
-Add tests. I had added tests in my last commit, but it
got lost somehow.
-Use every for computing revision ranges.

File Tools/GardeningServer/ui/ct-commit-list.html (right):

https://codereview.chromium.org/406163003/diff/20001/Tools/GardeningServer/ui...
Tools/GardeningServer/ui/ct-commit-list.html:37: this._revisions =
Number.range(this.first, this.last).every(1);
1 is the default, you don't need to pass it, though every() without an argument
does look sort of goofy.
