Add setting to hide .git directory about reacto

[eveningkid]

I believe we should instead add an option to hide any file/directory starting with a dot.
Otherwise, show it with a higher opacity if the setting is disabled.
What do you think?

The idea would be more to hide all files/directories in a .gitignore also

I integrated details display for a current working project using git. A screenshot can be seen on #73.
For now, ignored files are still shown but a little gray left border will appear.

Should it be an option to simply not show them inside the file tree? Thanks for letting me know. :)

We'll then have two options: one to hide .gitignore files and another for any file starting with a dot.
I'll keep you updated as soon as it's implemented! :)

There are also ci files and environment files with a pre-dot. Files in .gitignore would be great. I think these files are used less then other and cleans the files-structure.

When I started working on the issue, I realized that this could be part of the git integration inside Reacto. This is the next task I'm working on at the moment. :)

It will soon be added, along with the git integration.

Added with #77!
