Allow sync of .htaccess files

Is your feature request related to a problem? Please describe.
It's not possible to synchronize .htaccess files. Even when not specifying its name in the config blacklisted_files.

Describe the solution you'd like
.htaccess should be syncable. Perhaps only if data is not in web server root or if web server if nginx. And, at least, provide an option to deactivate this protection (.htaccess are important for web developers). Perhaps some kind of magic rename should occur on the server side for this specific case (renaming .htaccess to .htaccess\011\011 for example), magic reversed when syncing to the client.

Describe alternatives you've considered
Renaming the file. Quite impractical.
