Create th:replace as a synonym for th:substituteby

[danielfernandez]

Create a new attribute called th:replace as a complete synonym for th:substituteby.

The plan is to completely replace th:substituteby by th:replace in a couple of versions, so with 2.1 replaceshould be added to the documentation instead of every appearance of substituteby, and a mention to substituteby should appear stating that although having exactly the same effect, it is no longer the preferred option.

th:substituteby should NOT appear as deprecated in 2.1

@ultraq you are a native English speaker... what do you think of this? Do you feel th:replace is a better word than th:substituteby? Maybe we could just keep both, but only document th:replace in the future...

I think 'replace' is better than 'substituteby', simply because it's a single word like most of the other processors, and so feels more like a part of the processor family that's been created. All the other two-word processors are there to convey additional meaning and distinguish themselves from their single-word counterparts, eg: th:classappend and th:class, the 'append' part shows that it does more than the standard 'class' processor.
