Howm re-start

Howm re-start

Howm appears to be well suited to the simplicity of GTD, much more so than the
overdone nature of org-mode.  I have moved the menu to this folder for two
reasons:
	1. to have it on any computer on which I install emacs.
	2. to make it not show up in the howm overview.

I have also removed unused templates, and
made the default capture template have a tag of "#inbox".
