Add .dropboxignore directory to exclude folders without using selective sync

Let me also say, that this is an issue that does not just apply to us few that commented on here. The internet is full of people wanting a feature like this: dropbox gitignore - Google Search. Many "solutions" have been proposed, all of which are either not updated in the last few years, actively broken by Dropbox updates or are utterly overcomplicated, like not blocking every file matching that name and instead having to select each one manually, defeating the purpose. None of the solutions is as simple and elegant as one built into Dropbox would be. Especially "moving the files out of Dropbox" requires lots of work and confusing file structures, defeating the purpose of easily syncing folders with my friends and colleagues.

A solution like this is required for many people to have Dropbox do exactly what they want and too many people have to live with workarounds, suboptimal solutions or even completely given up on that.

Please implement this feature! This is not directly meant as negative criticism, but as an illustration of the issue and its widespreadedness. I hope we can somehow get you to reconsider!
