Tentaculo support for remote work.

Tentaculo is a plugin embedded in your working software.
We will enhance it with support for several remote work protocols:

• FTP
• VPN (if it is slow)
• S3 API — supporting cloud storage (Amazon S3, Google Cloud, etc)

Tentaculo plugin will also be embedded in Cerebro itself, for the ability to download files using new protocols directly from applications.

Also, we will add the option to download references for software that works with files containing links to other file resources. References will be identified using custom processors because reference search greatly depends on both the software itself and the file formats. Tentaculo itself will be responsible for downloading and updating reference files.
