Prepare for PseudonameAPI 1.4 release

The PseudonameAPI is preparing for release 1.4. This release adds rate limiting and API method changes that will necessitate Pseudoname updates. This change also solves the problem discussed in #9 and the existing CAPTCHA system can now be removed.

Alias creation not working

I have created an alias, I've got the «Success!» message but in reality it doesnt work, all the mails sent to it are always returned with a message «address: unknown user».

Need a CAPTCHA system

Sometime, over the course of the last 4 days, the system was brute forced and 800+ illegitimate aliases were created.

This incident did not impact system uptime and the illegitimate aliases will be purged by end of day, however this serves to highlight the need for a CAPTCHA type system.

Luckily, the attack wasn't sophisticated enough to vary the pattern of alias names, making them easy to identify (see examples below):

This is obviously a subset of the 800+ aliases, but as you can see, they follow a common structure. Given the low number of aliases created (~800 is pretty small, all things considered), I suspect that this was a proof of concept test and not a full scale attack. Regardless, a CAPTCHA seems necessary.

The copy alias button is not working on mobile

I’ll need to investigate this a bit more. I tested it on Safari on iOS and it didn’t work. It is working on desktop however.
