Remove all references to Pokemon for template to be useful

[AleksandarDev]

Statement: template currently requires too much editing and cleaning before it can be used in new project.

Proposed changes:

1. remove all pokemon related stuff and replace with something every app requires
2. replace all pokemon related examples and explanations in Readme
3. remove all "Enterwell was previsously ... and now we ..." paragraphs from Readme - this is not a migration guide
