Blind Accessibility

Nobody has claimed this yet.

**Is your feature request related to a problem? Please describe.**
This feature request is to mainly add/improve screen reader support. Right now, the start screen is somewhat accessible. With a screen reader, I am able to see the buttons for creating a new project, opening a project, creating a new map, and creating a new tileset.

**Describe the solution you'd like**
The idea is that through QT's own accessibility features, and perhaps through other screen reader support, we can create a mostly usable program for the visually impaired. This should have minimal impact on other features of the GUI.

**Describe alternatives you've considered**
I've considered first just making an entire new setup, but TMX is far too used and valuable. Even building a fully featured TMX editor would be cumbersome. As far as alternatives to the idea above, it is possible, and might be necessary to add an internal voicing system to maintain cross-platform compatibility.

Start by examining the start screen and the existing Qt accessibility behavior described in the issue, including project, map, and tileset creation buttons. Define the scope for usable screen-reader support across the GUI and verify that the changes work for visually impaired users without disrupting other GUI features.
