Resolver must account for inter-project references

[retailcoder]

The resolver currently escalates its searches like this:

1. Look at parameters and local-scope variables
2. Look at module-scope members
3. Look at project-scope globals
4. Look at the global-scope stuff

It should be this:

1. Look at parameters and local-scope variables

2. Look at module-scope members

3. Look at project-scope globals

4. Look at the global-scope stuff

   4.1. Look at exposed members in referenced VBA projects
   4.2. Look at exposed members in referenced COM libraries

Fixed with #1429
