This patch updates the www/opera port to 7.50. It also
renders the www/opera-devel port obsolete (since this
version is newer than the development port), so I propose
IGNORE= "Main port has a more up-to-date version"
to the Makefile of www/opera-devel until a newer
development version comes along.
I just saw that the linux-opera port no longer conflicts with this port. The
CONFLICTS= line from the Makefile should therefore be removed.
I'll handle this.
