Tidy fixed default WTK location, fix antenna-build.xml files

1. Multiple antenna-build.xml files refer to a fixed C:\ WTK location
 - change this to refere to one build-wtk-common.xml file that will
 allow for use of properties file, then look at WTK_HOME environment
 variable and then fallback to C:\ default location

2. Add to build-release logic to check for a .properties files.  Will
 use build-release.properties (git ignored to allow for custom settings
 ), if not will fall back to build-release.default.properties
Update to use bootclasspath appropriate to WTK in use

Nokia WTK requires all jars in lib in bootclasspath; SunWTK will
not accept that.
Update WTK Path to work with JavaME3.4 on Windows

WTK 2.5.2 is the exception for not working with all jars in lib in path
Update to build correctly on Sun WTK and Nokia SDK

and with Nokia SDK on Windows.
