[Devel] testing value of avp that is not set

[Juha Heinanen]

i did some testing of the new pseudo variable capabilities and noticed
that i get an error

Feb  9 01:30:53 localhost /usr/sbin/openser[15198]: comp_scriptvar: invalid operation 20/3/1!!
Feb  9 01:30:53 localhost /usr/sbin/openser[15198]: WARNING: do_action:error in expression

in a test 

	if ($avp(i:105) == 1) { ...

when $avp(i:105) has not been set.  

in order to get rid of the error, i need to change the test to

	if (is_avp_set("$avp(i:105)") && ($avp(i:105) == 1)) { ...

in order to make things more user friendly, would it be a better to make
the set test automatically before actually comparing the avp value?
