Re: Various patches

I will commit the changes on the "general-fixes" branch to svn on
Wednesday, unless someone objects. The patches are:

$ git log remotes/git-svn..general-fixes|git shortlog
Thomas Leonard (11):
      Improved error message when trying to call a named method on a verb facet
      Show stack trace when updoc gets an unexpected exception
      Preserve source span information when building quasi-literal expressions
      Avoid Java 6 IOException constructor
      Fixed "make tarballs"
      Report source location when a uriGetter isn't defined
      Serialize Switchable refs correctly
      Add hostnames to the vat search path
      Added Java VatSeeder class to avoid thread-safely problems with Vat.seed
      Use makeSeedVat to make the parsing vat
      Use seedVat to create eval vat too

For full details, see:

http://gitorious.org/~tal-itinnov/repo-roscidus/it-innovation/commits/general-fixes

The new commits I haven't mentioned here before are:

- Preserving source span information for uriGetters (similar to the
quasiParser change).

- Adding hostnames to the search path. Before, we only added IP
addresses, but these often change. Now we include both the hostname and
the IP address, with the hostname being tried first. This seems
sensible, but perhaps someone could confirm?
