CompilePackage: option to compile dependencies

[mtorpey]

As discussed in Issue #49, it's hard to know when to compile dependencies on an update. Our current approach is to automatically run the build script on packages that cannot be loaded. Then we have CompilePackage as a manual workaround for any packages that are missed.

@james-d-mitchell suggests that it might be nice to be able to compile a package and all its dependencies, since this is something that comes up a lot (again, see Issue #49). This seems like a reasonable idea, either by an optional argument to CompilePackage or by introducing a new function with a name like CompilePackageAndDependencies.

Related: how about a CompileAllPackages function that runs the script on everything in the user package dir? Seems like this would be useful for things like updated GAP versions.

I think you can close this now, you resolved it right?

Not quite. We can run CompilePackage, but it doesn't compile dependencies automatically, which might be a nice addition later on.
