Removed the quickfixes from the Message datastructure as they give a problem in equality checks at this moment. The branch 'quickfixes-in-message' still contains the needed changes
Modified to use void instead of empty tuples to represent 0 keyword parameters.
Ensure file resolver does not return null, which can happen when it attempts to access an inaccessible file (e.g., because of security permissions)
Many checker updates, especially focused on serializing configurations and using serialized results
Commented out test that is not relevant with modified checker
Merge branch 'master' of github.com:cwi-swat/rascal
Switched keyword params back to value types so they can be serialized
Added 2 extra arguments added to "refresh", namely "event" and "user
tag". To the functions which return a figure defined "example.rsc" are
added the same two extra arguments. In the body of the function
handling events can be taken place (see example counter11).

The data type Figure is extended with the property "id". 

A step is made forwards to solve the problems of "extra_figure". 

"trcursor"  is extended with a boolean parameter  "deep".
added function call method that accepts keyword arguments
Removed System.err outputs and put them in the M3 messages
Merge branch 'master' of github.com:cwi-swat/rascal into rascalwithBM
