Release 0.86

This release is a collection of fixes to get Crashmail running on
modern 64-bit Linux.  This is the first release in which the
following tools all pass the test suite:

- crashmail (areafix)
- crashstats
- crashlist
- crashgetnode

Use of the legacy ulong/ushort types have been replaced by
the stdint.h uint32_t/uint16_t types throughout the code.
Merge branch 'master' into develop
more -Wall fixes

GCC version 4.7 reports a few additional issues that
GCC 4.2 didn't catch.
