Change the GMT default to use proper degree symbol for its intended use. We declare a bug on our usage of the ring symbol. MAP_DEGREE_SYMBOL can be used by those who prefers the wrong, smaller symbol. Also properly set negative numbers plotted using the minus symbol, use hyphen symbol otherwise, and use endash to indicate ranges. Also introduce the "@." shorthand to indicate degree symbol in free-form text so that it can be independent of the character set. Made changes in scripts that needed to set degree symbol via octal codes. Majority of PostScript originals will need to change (another PR).
Needed to add the new @. for degree symbol.
