Change permissions on upload

[anubisthejackle]

It appears that when I upload or create files with this extensions, they are automatically set to 0666 permissions. Is there a way for me to change the default mask for permissions? Specifically, I ran into an issue with my college course where I uploaded some files and the server choked on the permissions and returned a 500 error. I didn't realize it was a permissions thing, so spent a lot of time trying to debug a non-issue.

0666 isn't a terrible default, but it would be nice not to have to resort to WinSCP when I need to create my files, so I can modify them with this plugin.
