Add source to source manager - this includes initializing

alias -- alias under which source will be accessible. Also
controls several paths under which temporary data is stored
for the sources
db_path -- path to database with EVE data for this source
Optional arguments:
make_default -- marks passed source default; it will be used
by default for some actions, like fit initialization, unless
specified explicitly
