add <, >, and numeric = operators to pathquery language
Need to have less than, greater than, and numeric equals operator support in the
pathquery language so that we can do spatial and othe rimportant queries.

Included new terms in pathquery.dtd for searchmode:
equals (former "matches-exactly")
added support for them in QuerySpecification. Tested in Oracle.
For = and != operators: ='1' and =1 (!='1' and !=1) work in the same way for
numeric operands thus ='operand' is used only.
For >, >=, <, <= check for numeric operand is added like:
if (operand is Number)
else //character operand
