v1.3

Updated to version 1.3:
* v1.3
	- Added blank lines between MSTI regions for readability.
	- Modified the output of the VLAN list. If it is greater than 35
characters, it shows up one line below, so that the Root Port
information doesn't get shifted right.
	- Added output for the MSTP Configuration Name, Revision Level, and
Configuration Digest.
	- Fixed the logic for MSTP instances. There was an error so that the
first MSTI was being used as the results for all MSTI instances.
	- Updated the Readme with instructions on using the SLAX script.
	- Modified output to be shown to the user as it is generated, rather
than all at once upon script completion. This should create quicker
results for large numbers of MSTIs, so the user knows that the script
is actively working.
