Updated the display of kludge lines & header lines so that the label & value will be on one line if they fit that way, to save screen space and reduce the need for scrolling.  Also, added a couple of color configuration options to DefaultTheme.cfg: hdrLineLabelColor and hdrLineValueColor, which lets the sysop specify the colors to use for the header/kludge line labels & values.  Also, updated the readme file & revision history file.  This is still a 'beta' version but is fairly stable.
