SoE: texts, energy core, fragments, useful (#777)

* fix missing fields in custom prog balancing option
* fix typos and pep8
* update and implement pyevermizer 0.41.3
  * allow randomizing energy core
  * add energy core fragments (turn in at Prof. Ruffleberg)
  * rename some items to avoid confusion
  * differentiate between progression and useful
* remove obsolete 'Bazooka' group
* don't add items to the pool that get removed
