SCP: Cleaned up help for EXPECT and SEND commands.  Added optional case insensitive match option to regular expression EXPECT rules.
SCP: Added IF command and string comparision behaviors to the ASSERT and IF command operations.
SCP: Added numeric value comparisons to IF and ASSERT compares.

Compare operations will do a literal compare of basic string values unless the all of each string contains numeric data.  If numeric data is there then a numeric comparison will be made.  For example:

	If "+1" == "1" echo equal

will display equal, while the simple string comparison will be not-equal.
