[V3dot9] 3.9 gamma ready

[Damien Cassou]

Some notes about 7055:

- Killana:8888 is still referenced under Monticello (for the monticello 
package)

- Package Multilingual is modified in monticello (a star '*' appears in 
front of the name)

- Two updates are available in SqueakMap :
    - SUnit3.1.6 -> SUnit3.1.33
    - SqueakMap loader 1.05 -> 1.06

- The two opened workspaces are not saved and then a red border appears


Good work !
