Errors caused by incorrect entries in "name" field

I love this plugin and found it really easy to get started with.

One problem I had was that the “name” field, when creating a field with the field builder, doesn’t have any validation or explanation. I had errors with fields on post types not saving because I had given my fields names with spaces in. Perhaps it would be possible to do some validation on the “name” field when creating a field, so that this doesn’t happen; or at least a short explanation under the field.

Otherwise, as I say, a fantastic plugin! Thanks for creating it.
