trello label changes

[Harald Sitter]

alohas

in the past we used trello labels (the colored thingies you see on
cards) to label

- packaging
- programming
- qa
- not development
- sru
- security

starting with 14.10 we'll change that a bit because it hasn't been
terrible useful. we'll instead have the following labels:

- not development (every card not marked not development is considered
a development card)
- sru (only used once the board turns into a maintenance board)

of the remaining labels only one will be allocated to

- blocked (card cannot be moved forward because of other parties)

left over labels will be unused for the time being.

additionally starting immediately the 'security' label (color red)
will change to 'blocked' to denote cards that cannot be moved forward
at this time. blocked cards may receive poke attention (i.e. someone
poking someone to get it unblocked), but otherwise should not get
attention.
