Bug 11629: Revert obfsproxy to 0.2.4.
Bug 11658: Add support for proxies while PT lines are present.

This technically backports Bug 8402's patch, which will allow proxies to work
without PTs again.

However, PT+Proxies remain unsupported until we bump obfs3 to 0.2.9 and solve
bug #11535. Flashproxy and FTE may need similar bumps+tweaks to fully solve
bug #8402.
Add stopgap for shipping HTTPS-Everywhere.

Until bug 11630 is fixed we add a better stopgap than shipping
outdated HTTPS-Everywhere versions: we take the NoScript route and
download and use the .xpi made by the EFF.
Bump version to 3.6.1 and pin FTE to a specific hash.

FTE's tags are unsigned, so we have to use commit hashes.
Update changelog for 3.6.1.
Update NoScript.
Make 3.6.x officially the 'stable' series.
Add a tor-master version of #8402 for nightly testing.
Bug 11771: Verify all tags/hashes prior to each build invocation.

Only if VERIFY_TAGS=1 is set from the versions file though.
Make PT tags explicitly be git tag refs.

Otherwise, alternate named refs can be inserted and used instead.
Bug 11535: Add txsocksx dependency.

We not only add the txsocksx dependency but Parsley as well as it is
needed by txsocksx. We further avoid downloading vcversioner during
build time (that is during running the gitian-pluggable-transport build
script) pretending we already have it locally.
Rebased Yawning's patch to fix build bustage.
Extract Libevent version properly; code clean-up.
Document txsocksx commit version.
Add (unused) parsley and txsocksx vars so 'stable' can still build.

It doesn't use them, but the fetch and verify scripts expect them.
Revert stable twisted hash back to 13.1.0.
Bug 10120: Part 2: Refactor Windows descriptors.

We build the tools needed for the Windows descriptors separately and
preserve them. This does not (yet) include the tools in the Pluggable
Transports descriptor which will happen in an other commit.
Don't break stable and beta due to c67075a.
Go back to tag 0.2.13 as FTE master is broken.
Install fteproxy docs to the right place in the mac descriptor.
