Readme Update

Fix distance to next waypoint widget in QuickView.

This patch fixes a bug that display 0 for distances to waypoint more
than 10km.

Besides that, it also homogenize the naming of the label to
"distToWaypoint" instead of "distToWP". Old configuration files (in
home directory), should be hacked or removed in order to see this
change.

Reverting previous Installer commit

Figured out why command line builds were not working. To build Windows
release from command line you need msbuild …
/property:Configuration=Release

This fix was pulled across from current QSerialPort codebase. I looked
into pulling across newer version of full QSerialPort. While doing that
I discovered that the version we are using has already been hacked to
work with us. It was fairly involved to redo those hacks. So decided to
pull individual change across instead since our version is already not
clean. When we switch to Qt5 all this will go away.
