Improve stdout logs (color, alignment, compacity)

[aboellinger]

Problem

Finding relevant information in the console can be difficult, especially with when it's flooded with debug logs.

Solution

Rework the engine logging code so that the content that goes to Blender's console gets the following features:

• More compact and less redundant (reducing visual noise)
• Content aligned (reducing visual noise)
• Severity colored so that errors and warnings stand out
