#47 Tips don't implemented in PHP5 except for bars

[Ogi Bankov]

OFC version: Version 2 Lug Wyrm Charmer
Can't use custom tips for OFC_Charts_Line in php5-ofc-library. After browsing the sources it seems that tips are implemented just for bars.
If manually create a data file with tips like:
... "values": [ {"value":22, "tip":"Some custom tip"}, 255, 209,...
It works so it is supported by swf, but not by php interface.
