Simplify compilation process

[Samueltelegram]

Right now the process to test new code is to build prometheus -> rename to inject.dll manully -> copy files over to overwatch.
I wrote some powershell scripts to automate this process within prometheus/build.
This uses the existing solution file to build prometheus.

The exact workflow of prometheus/build/build.ps1:

• Check if $OverwatchDir isn't present OR no patched game is present

(on first run || no patched exe || moved OW directory)

• If so, build and run patcher, prompt the user to select the base exe
• Upon closing, write gathered $OverwatchDir to the settings.json

then:

• Builds prometheus
• Renames prometheus.dll -> inject.dll
• Moves all built files into $OverwatchDir

then run.ps1, uses the $OverwatchDir from settings.json to run the patched exe

build_and_run.ps1 combines both of these, so you can run this script after updating code to directly test it.
