wire up column config for resource

[bezhanSalleh]

this PR wires up the column and column span config for resources's checkbox when resource isn't simple.
this will allow to controll the checkboxes shown for permissions in the resources' tab separately from the other tabs column and column span config. previously the following two options were available but not wired-up.

->resourceCheckboxListColumns()
->resourceCheckboxListColumnSpan()

For checkboxes of other tabs and when resource is simple

->checkboxListColumns()
->checkboxListColumnSpan()

resolves #476
