Add preliminary module to cover 'Misfortune Cookie', CVE-2014-9222

The details are still largely missing, but we do know from public documentation that this affects RomPager < 4.34.

Validation involves tracking down or building a system that responds to /Allegro with a RomPager-like Server header.

Against a supposedly vulnerable host:

```
msf auxiliary(allegro_rompager_misfortune_cookie) > check
[*] 10.0.1.34:8080 - The target appears to be vulnerable.
[*] Checked 1 of 1 hosts (100% complete)
msf auxiliary(allegro_rompager_misfortune_cookie) > run

[+] 10.0.1.34:8080 appears to be vulnerable
[*] Scanned 1 of 1 hosts (100% complete)
[*] Auxiliary module execution completed
```

Against a supposedly invulnerable host:

```
msf auxiliary(allegro_rompager_misfortune_cookie) > check
[*] 10.4.25.240:8080 - The target service is running, but could not be validated.
[*] Checked 1 of 1 hosts (100% complete)
msf auxiliary(allegro_rompager_misfortune_cookie) > run

[*] Scanned 1 of 1 hosts (100% complete)
[*] Auxiliary module execution completed

```
maybe I'm missing something but where is the variable 'version' coming from here?
