Log Message:
Updated devtodo to 0.1.20.

0.1.20
- A few bugfixes.
- Added XML declaration parsing/saving. This is a stop-gap at best, but will
  hopefully be useful to some.
- Removed reliance on builtin regex library. Hopefully the completely broken
  version of glibc that instigated the inclusion of it is now out of
  circulation.
- Fixed a whole bunch of compiler warnings on more recent GCC versions.
- --not-done now marks sub-tasks as not done. Thanks to an anonymous
  user for picking this up.

0.1.19
- Updated my E-Mail address after about a year of having the wrong one :)
- Removed informational message at top of .todo files as it was rather useless
  and actually annoying to some people placing their .todo files under version
  control systems.
- Added a XSLT -> XHTML+CSS transform from Francesco Poli.
- Added a bash completion script from the Gentoo projects maintainer Aaron
  Walker.
- Fixed seg fault visible on 64-bit systems but present on all. Thanks to the
  Debian project for notifying me and providing a fix.
