[dev] horde blocks

[Marko Djukic]

since portal and giapeto share a lot of the horde_block functionality i was
thinking how to standardise a bit.

some of the block code from portal i'd like to put into a separate Horde_Blocks
class to deal with blocks as a collection, and then Horde_Block (or maybe
Horde_BlockObject?) to deal with individual blocks? so both portal and giapeto
could access the same code?

another thought was to move some of the block setting up to standard horde_form
code?

opinions?
