Summary description:  eXercise Sheets IMproved

Announcement text:
 - switch to one sty file per package

 - use LaTeX's new hooks

 - declare undeclared variables

 - new exercise setup mechanism which clearly determines the difference
   between definition, usage, and printing of an exercise;
   this also solves the problem with added goals in the exercise body
   in a collection

 - re-write collection mechanism:
   * changes the behaviour of \collectexercises but doesn't require
     external files any more, and more importantly doesn't require
     inputting files several times for multiple collections
   * drop \collectexercisestype
   * new \(de)activatecollection
   * new options `collect' and `<type>/collect'

 - small improvements in performance

 - new parameters `within' and `the-counter'

 - make `no-files' the default, new option `use-files'

 - new examples

 - various small fixes
