Description of problem:
The server configuration page in Administration has url validation on the Register url field - so the previously accepted /zanata/register is now rejected as invalid
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. sign in as admin, go to Administration, Server config
2. Enter /zanata/register into the Register URL field (as indicated by the placeholder)
3. Press Enter or Save
Still reproducible in server 4.0
After entering zanata/account/register as indicated it gives enter valid url.
Valid indication/only accepted indication should have to set.
I've checked the source code history and we never allow '/zanata/account'. The url validator is always there and only allow valid url (e.g. http://zanata.org). Its just the placeholder is misleading. I will update the placeholder.
