Feature 02 signup user
This merge will include:
- The implementation of signup for a carer or user (If carer, both accounts are setup in one).
- Validation for each and every field which work independently of each other
- Forgotten password prompt
- Various methods for signup screen stuff
Fully working, thought it would be best for us to merge this ASAP rather than waiting on other sections, the signup method can always be expanded on but this way we don't do too much without merging.
