* include/, fgraph.php: Moved licence of libraries to LGPL.
* install.php: Added dependency check for several new includes
from pear (xml_rpc and DB), also graphviz twopi binary and check
in step1 for a writable config.php and ./include dir. Some other
minor fixes (esthetic).
* pandoradb.sql: Table tagent_data_image was still there. This
comes with next version (I hope), not this one.
* pandoradb_data.sql: db_scheme_build update and removed modules
components without proper id_module.
* networkmap.php: Another foreach() notice fixed.
* upgrade.php: Moved to contrib branch in SVN.
Old pandora SQL conversion files, deleted (was present in its branches).
