Revert "[INTERNAL] Remove deprecated and unused method from ITransmitter"

This reverts commit e48b02098e4975b6816fe1edcd91a91cbdd33a73.

The Whiteboard does not use a Server-Client architecture as far as I can 
remember, so this patch may break the functionality to use the Whiteboard
with more than 2 users.

[API] Revert 85d66af, introduce IActivityProducer and -Consumer instead

Thanks to Stefan Rossbach for pointing out a less intrusive way than
renaming the IActivityProvider interface to
IActivityProviderAndConsumer.

This patch deprecates the IActivityProvider interface and, in order to
take a first step towards the separation of concerns of Activity
producing and consuming, adds two new interfaces each of which is now
implemented by the AbstractActivityProvider class.

[API] Amend core filesystem interfaces

Under the headline of decoupling Saros from Eclipse, this patch amends
the Saros Core filesystem API by adding all methods that are actually
called on the instances of the Eclipse interfaces (objects of type
IResource, all its sub-interfaces, and IPath).

Please note that these interfaces are under development. They will be
simplified and will finally provide less methods with less parameters.
After all, they should hide IDE-specifics. For now, that simplification
is deferred until the IntelliJ adapters are written.

[FIX] Path-based editor closing was not working

The convenience methods EditorManager.isOpenEditor() and .closeEditor()
were not working because for finding the correct editor, they relied on
the equality of Eclipse's IResource and Saros Core's IResource (which is
always false).
This led to no compilation errors, because the equals() method is
declared on Object and takes any Object as parameter.
However, this defect did not lead to failures because (1) these methods
are only executed during inconsistency recovery which is seldom
necessary, and (2) even then, closing the affected editors does not seem
required to resolve the inconsistencies.

[FIX] Ignore already shared files while adding new ones to a session

When adding files (or more general, resources) to a partially shared
project, used to exclude already shared files from the selection.
That mechanism broke when the list of already shared resources was
changed from Eclipse resources to Saros Core resources (whereas the list
of selected resources remained Eclipse-ish).
This patch restores the old logic.

However, higher-level logic seemed to cover that defect, so that no
failures were observable.

in order to avoid accidental overwrites.

Also, this patch cleans up the verification logic as it was almost
