#33 Model Explorer doesn't work properly with model in packages

[Enrique Esquivel]

When you define a model into a delphi package all
controls in the model explorer are disabled. They're
enabled only when any application is open before than
the package.
In some situasions the $R directive which includes the
model is changed from {$R .mdr} {XXXModel} to {$R
'.mdr'} and io doesn´t find the model.

there are two bugs to fix:

Bug: The model is missing when reside in package and changes
the package content
This bug is reproduce in D6 and D7 with the last subversion
source.

Steps to reproduce:

1. Create a package
2. Create a unit for the model
3. Create the model, the source of the package now contains
   the model's resource:
   {$R *.mdr} {Model}
4. Add a unit to package, the model's resource included in
   the package code is changed to:
   {$R '*.mdr'}

When try to compile the package the follow message is showed
[Error] RLINK32: Error opening file
"C:\Projects\PackageTest*.mdr"

Bug: The InstantObject Model Explorer doesn´t work on
packages without an opened project

source.
