[TxMt] project: duplicates can be added and lack of alias

[Timothy Bates]

Hi,
one thing that stops me from making more use of the project view is the
problem of losing files when they are renamed or moved outside the textmate
environment. 

Is there a reason that the project view doesn't store alias's? These allow
you to track files seamlessly.

Also, it seems wrong to be able to add a file twice to the project:
shouldn't the project detect that the file is already there and just
activate it's view tab?

It the purpose is to allow multiple views of the same file, then this might
be better achieved by split panes?
