Fix error being thrown in isInNet() PAC js

Fix error being thrown in isInNet() PAC js.

Mozilla is using notation which treats regexp like a function:

var regex = /foo/;
var result = regex("str");

However v8 does not allow this (nor does IE), so we rewrite it in standard form:

var regex = /foo/;
var result = regex.exec("str")

Also finishes off the tests in pac_library_unittest.js. I didn't test every single permutation of dateRange() and timeRange() as there are way too many; but did hit most common flavors.

LGTM

is this a v8 bug then?

IE doesn't support this either, so probably not a big compat issue. I will file
with V8 anyway to be sure.

The issue is, that in Firefox, a regexp object is treated like a function in
that you can invoke it with parameters:

var regex = /foo/;
var result = regex("str");

The above is equivalent to the standard mechanism:

var regex = /foo/;
var result = regex.exec("str")

I've updated this CL to simply use exec().
