double_click_delay should only add a delay to the click and block in question

[GreyXor]

The delay for a double-click should be configurable for individual blocks or clicks, rather than being set globally. This way, only the specified click on a particular block will have the delay applied.
Also that would be nice to have DoubleRight and DoubleMiddle too.

The problem is that I've added double_click to only one block, but as a result all my blocks are slowed down, even the others don't use double_click
