Add a hint of the TLD when registering a domain

[Luis]

When clients fill out the fields for domain registration they're asked to fill the SLD, but sometimes they could make a mistake and put the complete domain name.

Please consider:

1. Sanitize this field, when saved, remove the TLD if necessary.

2. Add a little hint at the side of the field, to indicate the TLD is already included (See image below).

 

Thanks.
