Wasp 0.5.005b

New beta version with a few bug fixes and few new features in the aggregation graph generation and in the DisCo save/load components.
New features:

• #6 The Aggregation Graph component now allows to set a tolerance value, below which parts are considered connected. This is useful when working with interlocking connection with multiple members in the same connection, allowing to increase tolerance to consider elements connected even if there is a gap between the connections.
• The DisCo Save and Load component are now able to track data about the part owner and freeze time. These values are stored in the part as attributes.

Bug fixes:

• #5 Global constraints did not handle the required/optional parameter properly. When one part had a required constraint, the optional constraints were ignored. Now they are handled properly.
• The internal function compute_possible_children did not handle constraints and collisions, now this is possible.
