Changed website and source links for mSIGNA.

[CodeShark]

I would like to change the URLs for the links to mSIGNA.

@CodeShark For tracking purpose, you could also simply use the referer field from the browser since your website also uses https instead of requiring the user to pass through a redirection.

[CodeShark]

@saivann Yes, but that relies on the browser complying and also is not as extensible and flexible as this approach. This way I can continue to add arbitrary tracking fields.

[CodeShark]

@saivann Also, using the referer field won't help me track visits to pages outside my site (like github).

@CodeShark Redirection is very slow here, can you fix that? Also you may want to make sure these links won't break in the near future.

[CodeShark]

@saivann Looking into the slowness issue - that is a bit of a problem. The links won't break unless the server dies.

[CodeShark]

@saivann Try the links now - I think I found the problem with the slowness issue.

I tend to prefer keeping the real links but don't see any serious harm with helping you with the redirects, so in the absence of critical feedback, this pull request will be merged on December 1th.
