Modes about beautyxt

Now that .md files are also part of BeauTyXT, I would like to propose few changes:

File types:

1. .txt Text file
2. .md Markdown file

Modes:
1)a) Viewing Text Files [Text Viewer]
1)b) Editing Text Files [Text Editor]

2)a) Rendering Markdown Files [Markdown Renderer]
2)b) Editing Markdown Files [Markdown Editor]

The text mentioned inside the [] is what I am proposing to add in place of the now present "File Editor" text in the topbar.

NOTE : for this design to be more cohesive, I would say the filename should be present in all modes to avoid confusion or be present in the file properties dialogue (the latter seems less bloated to me).

Of course this means adding the same mode switching button present while editing a Markdown file.

Edit : I came to this removing of "file editor" dialogue since it doesn't make sense to me since it can't edit all files and also the app renders some too. Also ignore the original proposal.
