Updated XINDEX

This build updates XINDEX with bug fixes discovered after the certification of XT7.310001. The bugs are:

• XINDEX routine name printer when collecting routines still assumed that routines were 8 characters or less long. Now they are assumed to be 16 or less (DJW).
• XINDX10 check for contents for data in M fields previously only identified M fields as those with K in the field specifier. Now the input transform is checked as well; and the field is considered an M field if
  the input transform contains a call to ^DIM (DJW).
• XINDX9 always uppercased labels in remote routines. Non-VistA routines could have lowercase labels, so this falsely resulted in XINDEX claiming that the labels didn't exist when the lowercase labels actually existed. This is now fixed (SMH).
