Folder tree should hide .DS_Store & friends

[peterflynn]

1. View a folder in Finder
2. Open that folder in Brackets

Result:
.DS_Store file is listed in root of project folder tree UI

Expected:
Low-level OS files like .DS_Store and Thumbs.db should be hidden from view pretty much always.

Debatably, all dotfiles should be hidden from view... at least by default. (examples: .git folder, .svn folder)

There are a few things we could do here:

a. Filter just .DS_Store and Thumbs.db, by name
b. Filter all hidden/system files by looking at their attributes (probably requires app shell work; I'm also not sure what attributes, if any, are set on OS X to distinguish files like .DS_Store from other .-prefixed files)
c. Filter all .-prefixed files, by wildcard (plus filter Thumbs.db by name)

[peterflynn]

For the record, I decided to go with approach C -- seemed like the best bang for the buck.

Closing now that the fix is merged in.

Strangely, this seems to be resurfacing. I suspect it may be a plugin that's driving it on my build but I'm not sure which plugin it would be. Is it best to open this at the project level or reach out to the plugin authors?

@crispen-smith Use Debug > Reload Without Extensions to see if it's caused by an extension. If so, read this article on disabling extensions individually to try to figure out which one.

@redmunds I've been trying to replicate consistently. It seems to be a very intermittent thing which occurs on certain actions. Haven't yet been able to trace it.
