[FIX] link_tracker: prevent downloading big or non-html files

link tracker tries to get title from HTML, but the url may be not an html page
or too big html to process. It's a waste of bandwidth, but may also lead to a
Server Memory Limit error.

As a solution, make HEAD request and don't proceed to GET request if it's not an
html page or it's too big. Also, limit page downloading to 50KB.

STEPS:

- Have a standard database with link_tracker and mass_mailing.
- Create a new mass mail MM
- Add a link to a large file in MM Mail Body
- Click "SEND"
- Go to Settings / Technical / Automation / Scheduled Actions
- Open the "Process Mass Mailing Queue" or "Email Marketing: Process queue"
- Click "RUN MANUALLY"
