Validate data size for proposals only (#2004)

Browse Source 
There are no watchdogs and it makes no sense to limit triggers by size (invalid triggers are going to be voted down anyway).
512 bytes should be more than enough for any proposal - the only value we do not check size of is URL and with 512 bytes total limit URL has space for almost 300 bytes.
