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.
CNG-12, CNG-21, CNG-28, CNG-29, CNG-36: Add comments in original files so when they are altered, copies made for CNG should also be updated so they work fine with rest of subprojects.
