[Cuis] Cypress compatibility

[Juan Vuletich]

Hi Folks,

Cypress is a project by Dale Henrichs with the objective to create a 
cross-dialect package file format. Cypress is available for Squeak, 
Pharo, Gemstone, Amber and now Cuis. Dale himself did a preliminary 
version of Cypress for Cuis some time ago. Today I updated the code at 
https://github.com/CampSmalltalk/cuis-cypress and it is now working.

To use it, please update your Cuis image to #1307, or get an updated 
image from https://github.com/jvuletich/Cuis .

Cheers,
Juan Vuletich
