[cl-ppcre-devel] documentation in 1.3.1

[Sébastien Saint-Sevin]

Hi Edi,

The documentation is wrong since the patch included in 1.3.1.

- It should mention that regex-replace-all returns a second value "matchp" as regex-replace does.
- The examples needs to be updated to reflect the introduction of this second value.
- The changelog should also mentioned that regex-replace-all was updated.

Cheers,
Sebastien

PS: one day, I will learn how to submit nice diff patch... on my windows machine :-)
