Multiple Select on buffer and deletion only deletes first in selection
When you want to delete some buffers, you can select multiple buffers and then use the contextmenu to select "delete buffer". Then only the first clicked item is deleted, not all
Expected: every selected buffer should be deleted.
Two ways to solve:
1) implement a "delete all selected"
2) don't open the contextmenu when multiple buffers are selected.
I guess this is also happening to "hide events" and other stuff in the context menu, but I only tried "delete"
Quassel no longer gets a nervous breakdown when you select too many buffers - fixes #432
Handle multi-selections in BufferViews sanely.
This means that actions like hiding and deleting buffers now also work if multiple buffers
are selected. This is true for all displayed actions, i.e. you can hide events in multiple
buffers at once, or send CTCP commands to multiple nicks, etc.
(Finally) fixes #432.
