clean up build

• provide shell script build_local.sh
• rename test dir to local
• move all ant dependencies from .gitlab-ci.yml into shell scripts
• rename ant default build target to build
• add to build.xml:

!!! The rule is, the first line that sets a property wins. !!! The construct is usually used to include a file called build.properties. This is a convention used so that you can override default values for your local build environment, without having to modify build.xml (which may, after all, be a shared file, under version control). This means that build.properties should probably not be under version control (add it to .gitignore under git).

• redefine properties according to the aforesaid
• include generic SADE build.properties
• use setpermissions (ant v1.10+) for chmod +x bin/*.sh
• rename default lucene config files
• use gitlab-ci variables to load build properties according to the branch the build is running on: example
