Eliminate the use of Workspace2D workspace properties

[Russell Taylor]

This is for input (or InOut) properties only. They should all be able to use MatrixWorkspace, even if the algorithm doesn't really make sense with 1D/single value workspaces. This will allow the algorithm to work with an EventWorkspace as input.

The following algorithms need to be looked at (although some will just have a Workspace2D in the output properties):

(In [5120]) First batch of algorithms with Workspace2D workspace properties changed to MatrixWorkspace. Re #1368.

[Russell Taylor]

(In [5121]) Checked in local changes by mistake. Re #1368.

(In [5129]) Eliminate Workspace2D input properties in CurveFitting. Re #1368.

[Russell Taylor]

(In [5131]) More Workspace2D property eradication. Re #1368.

[Russell Taylor]

(In [5142]) More Workspace2D hoovering. Re #1368.
