Add <> to general T_SYMBOL RE and move it after the special cases. 

This patch add (I believe back in) the < and > characters to the
general T_SYMBOL regular expression. The match was also moved after
the special T_SYMBOL cases so that flex would match them correctly.
Flex matching rules are longest or if a tie the first.
