Fix: Projects finished by Techprof Persona Core should no longer be stuck in the research queue.

The issue should resolve itself when reloading the save.

- Delay layout generation and background layout generation should correctly preserve the research queue in the save file. (So with delay layout generation option on, and there's anything in the research queue, layout is generated when loading saves)
- Apply word wraps on research project names for better display.

Fix an old absurd issue of research projects ignore their hidden prerequisites.

New option:

DON'T IGNORE HIDDEN PREREQUISITES: Default is `true`. So you will notice a drastic change of your research tree when first loaded your research tree after update.
Please leave this option on except your existing save game heavily relies on a strategy with the original behavior of ResearchPal.

Fix the color of numbers in search mode.

Supports numerical display of research progress!

Hold shift to display the leftover points of all on-going research project.
When zooming out, hold shift to replace the name with research progress.

New options:
- Always Display Progress: Always show the leftover points, doesn't affect zooming out. Default is false.
- Research Progress Tooltiop: For ongoing projects, display an additional tooltip indicating the research project. Default is false.

Known Issue:

Currently the tooltip system isn't working properly, so that heavily affect the progress tooltip as well. If that doesn't work for you, just turn this option off. I have no idea why it's happening.

- Now tech-print tooltips should display consistently
- Search result will pop up after a short while of detecting absence of input, instead of popping up on every character typed.

Now the highlight facility should completely work.

Rewrite the highlight detection logic, now highlights should work regardless of zoom level.

Known Issue: Some edges are still incorrectly highlighted.

Adds an option to support background layout generation when game loads.

Please leave feedback about whether that works as intended, as I intend to make it a default in the future.

Resolve an issue in legacy code causing an infinite loop.
