Memento.nsh: Enhancing Usage Instructions

Hi,

I stumbled upon an omission in the Usage Instructions of Memento.nsh.
Doing the steps as described leads to an error message during compile:

Error: resolving install function "__MementoSectionMarkNew4" in function "__MementoSectionMarkNew3" 

Just because I had a printout of memento.nsh I quickly found the

!define MementoSectionDone

which I inserted after all MementoSections....and the project compiled.

So maybe someone should just insert another step between step 5 and step 6 of the usage description::

"Insert a {MementoSectionDone} after all MementoSections have been declared."

Thanks, added.
