The 2.2 installer does not contain overlays

[Tdue21]

Describe the bug
When installing a fresh 2.2 there are no overlays available, but the default Gear, Chrome.

To Reproduce
Steps to reproduce the behavior:

1. Uninstall any previous TokenTool installations.
2. Remove the ~.tokentool-rptools if it exists.
3. Install TokenTool 2.2.
4. Start TokenTool and observe the lack of overlays.

Expected behavior
I expected the default set of overlays to be included.

TokenTool Info

• Version: 2.2.?
• Install: New

Desktop (please complete the following information):

• OS: Windows
• Version 10

Additional context
If I install TokenTool 2.1 FIRST, and THEN 2.2., the overlays are present. So it seems that the overlays have been left out of the installer.
Trying to restore default overlays on a clean 2.2. does nothing.

Problem wasn't that the overlays weren't in the installer package it's that the prior method of using Reflection to copy them into their folder didn't work with the new modules/JFX approach.

Reviewed PR. Overlays now installing as expected.
