Enhance entry form

Enhancements to the entry form - eg search by rating code / PNUM, and anthony finding tony etc. Make it clearer that the fields populated by the lookup player button can't be filled in manually

If the ECF or Chess Scotland database does not have someone's FIN in a FIDE event, they get two versions of themselves in the selection list: one with a FIN and no ECF code, and one with an ECF code and no FIN - possibly it should let them enter their FIN if they know it ?

Make the congress entry screen clearer - maybe one step to say who you are and a second to pick yourself from the grading list. Perhaps allow Tony to search for Anthony, Bill for William.
