Feature/conf in one place
- added a ./conf directory and a ./conf_example directory
- the ./conf directory is where users place all their custom configuration files
- both the build script and the run script will then load the configuration from the ./conf directory and copy it into appropriate places
- see the ./conf_example to learn what configuration files to place in the ./conf dir
- reworked scripts to used shared resources
- moved the jetty distribution into the ./lib directory and then use jetty base in ./sparql_triplestore
- changed built in tool loading to be loaded the same way as custom tools
- changed powershell exec in the analysis adapter to print exceptions properly
- changed linux exec so that the script contains a /bin/bash -c "$1" and the string to execute gets passed as the $1 to the script
