v1.2.0 - Encoder feature merged

• Moved encoder thread from main.cpp to encoder.cpp
• Added "laptop mode" - deep copies frames when recording, thread-safe when on CPU power-saver mode.
• Prevent recording turning on when still encoding last recording session, only an issue when on laptop power-saver mode.

v1.1.0 – Toggleable screen recording

• Press R to toggle screen recording.
• Multithreading (encoder thread and render (main) thread) and async read-back PBOs are now separate toggles.
• Press P to toggle PBOs.
• Press T to toggle encoder thread for multithreading.

I have noticed on my laptop that when recording is ON and switching from encoder thread ON->OFF, the program crashes. Also when going from full-screen->windowed can crash the program as well. When using a machine with a not-so powerful CPU, try not to do anything that may stall the program abruptly like a fullscreen->windowed toggle, or turning OFF the encoder thread.
