[RenPy] Skill Tree

Skill Tree is an advanced system written in Ren'Py scripting language. 

The lines visible in the preview images are dynamically generated using code. The system is built around renpy.Displayable and renpy.Render.

Features:

• Unlock skills by meeting requirements such as skill points and unlocking prerequisite (parent) skills.
• Reset entire skill categories and recover spent skill points.
• Set multiple requirements for unlocking a skill, allowing connections from several other skills.
• Automatically choose the best calculation formula to render paths between skills based on their positions.
• The skill tree viewport adjusts its size automatically based on the placement of the furthest skill (the viewport is not a frame with the light blue borders in the preview images; the viewport is inside that frame; it's draggable and scrollable)
• Automatically change the color of lines connecting skills based on whether the next skill is/can be unlocked.
• Tooltip is shown after hovering over the skill icons (visible on preview images)
• Supports Ren'Py rollback.
