Contenttypes give unclear error on saving when the extension is not configured properly

[ankedsgn]

Hai hai!

1st of all, thanks for the extension. Very handy, should actually be somehow a part of the Bolt core, since it adds a logical functionality to the blocks that are in Bolt core.

The issue:

It causes and error when you have used a field in the config file that the extension cannot deal with. For instance: Image field / select field.

What happens:

Unclear error when saving the contenttype: Page could not be saved. Notice: Array to string conversion

What would be a better solution:

An error somewhere saying: You have an error in the config of the searchable content extension, line X or something helpful like that.

Thank you!
