Progress OpenEdge 11.6 added a new C-like single-line comment syntax; such
comments begin with `//` and proceed to the end of the line.
Add a new syntax group `ProgressLineComment` to implement highlighting for this
syntax. Rename the existing group from `ProgressComment` to
`ProgressBlockComment`, and introduce a cluster named `ProgressComment` to
encapsulate both.

The Progress syntax file was last updated eight years ago, and the header
information twelve years ago. Attempts to contact the last known maintainer at
the email address listed in the file header (with the spam-prevention characters
removed) produced a delivery failure notification stating that the address did
not exist.
I intend to submit some minor improvements to this file. Per [1], I will assume
maintainership of it for the time being.
