Changed the parsing of lines in the settings file. Instead of stripping 

all the whitespace in line, first split the line into key/value pairs
(split by '=' sign), then trim whitespace from beginning and end of both
the key and the value.

This fixes the bug where settings that must contain spaces (pathnames)
are garbled when they have internal spaces removed.
