[Webtest] new custom test step added (fetchPop3)

[Luca Scheuring]

hello folks

I've added a custom test step called fetchPop3 to the webtest community
site. it allows accessing a Pop3 Mailbox and fetching a specific mail. Once
the mail is stored in a local file, you can use the invoke step in
conjunction with the file protocol to access the mailtext. This enables you
to use the common webtest steps like verifytext or storeregex to process the
text of the mail.

we currently use this step to check
- if an eCard mail gets delivered and if the link in the mail to fetch the
eCard actually works
- the 'change email address' procedure where the user needs to click on a
link in a mail to confirm the new email address
