yasql try to use perl err() function and fail to compile/run.
	Also give some warning about deprecated functions.

Fix: Change err() with die(), replace \1 with $1, add some missing \
	Also bumped PORTREVISION to 1 (full patch attached)
How-To-Repeat: 	# cd /usr/ports/databases/yasql && make install clean
	# yasql
	syntax error at /usr/local/bin/yasql line 177, near "err"
	syntax error at /usr/local/bin/yasql line 180, near "}"
	Execution of /usr/local/bin/yasql aborted due to compilation errors.

	After substitued all err() with die() yasql start but if you use
	perl -w `which yasql` you can also get this warnings:

	Use of "do" to call subroutines is deprecated at /tmp/ya line 2407.
	Use of "do" to call subroutines is deprecated at /tmp/ya line 2410.
	\1 better written as $1 at /tmp/ya line 2876.
	\1 better written as $1 at /tmp/ya line 2890.
	Unrecognized escape \G passed through at /tmp/ya line 3565.
	Unrecognized escape \S passed through at /tmp/ya line 3565.

	First four lines are self-explained, last two have a missing "\"
	in the help section (to correctly show as "\G" asking for help).
