ISSUE-72: On OSX, disable smart quotes in the editor.

[dmalec]

Resolves #72 Resolves #162

Summary

OSX provides smart quotes by default systemwide. Under wxWidgets 3.0.x, there does not appear to be a clear approach to disabling this. Under wxWidgets 3.2.x, it is possible to selectively override the systemwide setting on a per text control basis.

Testing

Used the test plan outlined in issue #72 and verified that:

1. On OSX w/ wxWidgets 3.2.x, the text control no longer does smart quote substitution regardless of the systemwide setting.
2. In other cases, the behavior remains the same as it was previously.

Test Environments

• OSX Catalina (10.15.7) w/ wxWidgets 3.0.5
• OSX Catalina (10.15.7) w/ wxWidgets 3.2.2.1
• Windows 10 Pro (19045.2364) w/ wxWidgets 3.2.2.1
• Ubuntu Jammy (22.04) w/ wxWidgets 3.0.5
• Ubuntu Kinetic (22.10) w/ wxWidgets 3.2.0

I think this also will turn off smart dashes, which sounds like feature, not a bug :)
