[V3dot10] Do in a workspace and say if could build

[Edgar J. De Cleene]

In a Worskpace of 7105
Utilities readServerUpdatesThrough: 7108 saveLocally: true updateImage: true

And 

ReleaseBuilderFor3dot10 new updatePackages: 'Compression-edc.12(8).mcd
EToys-edc.27(23).mcd
Files-edc.23(20).mcd
Installer-edc.3.mcz
Monticello-edc.314(311).mcd
SMBase-edc.88(86).mcd
ScriptLoader-edc.326(sd.324).mcd
System-edc.106(104).mcd
SystemChangeNotification-edc.2.mcz
Tests-edc.28(26).mcd
Tools-edc.84(79).mcd
Universes-edc.23(ls.21).mcd'

When some confirm this is working, I remade all from this point.

Repositories was:
My own dir package folder (always is used)
Copy the .mcz to 310 for any could try

Very thanks to Ken
