Update Version 1.02a minor bug fixes for UI

Hello everyone thanks for using Janis AI. This a is a minor update for a couple of UI bugs.

-Fixed an issue where creating a persona would save it's system prompt as html and not plain text.

-Fixed an erroneous error message when starting the program.

Also, the installer is now being distributed in two versions. One with the model installer, which will automatically download and install the Mistral Hermes model into the programs model folder and one with just the Janis UI and no model installer. 

The latter is useful for those who want to just patch to the latest version or just want the Janis UI and already know how to find and install their own gguf models from sites like Hugging Face.
