convert FIXME=* to fixme=*

[mkoniecz]

What steps will reproduce the problem?

1. tag node with FIXME=geometry and building=hangar
2. run validator

What is the expected result?

Validator offer to change FIXME=geometry to fixme=geometry to help eleiminate FIXME duplicating fixme tag.

What happens instead?

Validator is not proposing tag changes.

Please provide any additional information below. Attach a screenshot if possible.

I can implement this, after confirmation that it would not be rejected.

@matkoniecz Thanks for the links! I'm glad this was already discussed since it saves us time. I read through the mailing list discussion and it convinced me that we should definitely deprecate FIXME in iD. Most people agreed that FIXME is dated and wrong. Another developer even mentioned how FIXME caused them hours of extra work. The disagreements concerned the necessity and effectiveness of the edit. Responding to the primary arguments I saw against your bot edit:

FIXME should purposely cause validator tools to flag it by being all capitalized.

A validator tool doesn't need special capitalization to flag something. In fact, having two tags makes it more likely that a validator will miss a fixme.

Fixmes aren't important enough to create new entity versions over.

Users would manually be updating features in iD, so I think creating new versions is warranted.

A single bot edit won't prevent future uses of FIXME. Editors should handle this.

This is the part we can address!
