[pbs-devel] [PATCH widget-toolkit v4 2/4] toolkit: add markdown based NotesView and NotesEdit

[Stefan Sterz]

adds a universal version of NotesView and NotesEdit to the widget
toolkit that is compatible with pve and pbs. this avoids maintaining
duplicate code in pve and pbs, but since the original versions were
very tightly integrated with pve-manager, changes are required to
make them compatible with pbs. changes include: making the tbar
configurable, setting the url differently in a pbs context, and
allowing the caller to set the onlineHelp field.
