This implements Jamie's suggested fixes for a screenreader issue when the skeleton UI is enabled. Most of the work here is just pulling out pieces from the files we needed to include in mozglue so that any references to, say, nsString or other pieces from libxul either no longer exist or are only included when building libxul. In a few cases this meant creating whole files to house single functions, which isn't so pretty, but it was the best I could come up with to get the job done.
