LDEV-2915: Add tokens to LAMS DB scripts. The tokens are replaced during build with properties taken from lams_build/*.properties files. Make lams_build/build.properties an optional file included before OS-specific property file, so computer-specific paths can be defined there.
LDEV-2901, LDEV-2902: Move classes generated by Eclipse to different directory than Ant generated ones so they do not overlap and product errors. Classpath in JAR/WAR manifests is not needed as JBoss Classloader takes care of dependencies. Manfiest was moved to a central location and is customised only with product name and version during JAR/WAR build.
