This reverts commit 8e55e36c.

Refs #9059

Mainly removed Poco includes and used forward declarations instead.
Unsuprisingly this has affected some algorithms.
Refs #8784

The shared_ptrs held in WorkspaceProperty were set and still held by the
AlgorithmProxy object until it got knocked off the AlgorithmManager stack.
This gave the impression of a memory leak if an algorithm failed when
in fact the references were just being held too long.

to algorithm base classes.
Refs #4218

Also some const-correctness.
