debian/control: add texlive language build-dependencies
OrderedTask: invoke ScanActive() in UpdateGeometry()

Update the active_state attribute of all task points.  Fixes a crash

Revert "XML/Node: use std::swap() in move operator"

This reverts commit dfeee6b53cf55eca27f03aa59b3a5f244d9fd213.

The commit caused a memory leak when assigning a child node to a
parent, because the "other" instance was never freed.
XML/Node: allow nested assignment

Make sure the "new" Data object doesn't get destructed before its
Ref() method gets called: reference the new one first, then
unreference the old one.
debian/control: install all manuals
TaskLeg: add missing return in GetScoredDistance()

Fixes crash after running into gcc_unreachable().
TaskLeg: remove unreachable "breaks"
Makefile: bundle libgcc.dylib and libstdc++.dylib on Mac OS X

Don't link the gcc libraries statically and bundle the two libraries
inside the DMG.  This is necessary because the latest MacPorts gcc
packages don't ship libstdc++.a, and the bug report on the MacPorts
bug tracker was closed as "WONTFIX":
