pgxn-sync moved to root (next to server-api/server-ui), also set ug+x
modified configuration of the API/UI to use dictionaries in the 'config' module
fixed the shebang to use 'env' and not /usr/bin/python directly (which does not work with virtualenv)
added a simple INSTALL guide, and one related TODO item (hardcoded API URIs in the UI templates)
