server: Added tool which allows to uncomment the JCIP annotations. From now on, JCIP annotations must be still used to document the thread safety. However, they have to be commented by prefixing the lines with "// JCIP ".

Examples how to toggle the comments in the code (executed in project root directory):
Comment:
./bin/toggle_jcip_annnotations.sh -c java/
Uncomment:
./bin/toggle_jcip_annnotations.sh -u java/
