Default hammer configurations

[DESTROYGIRL]

Description

Default configurations for the valve hammer editor (not hammer++) in our steam install
This also moves our FGD out of the assets repo and into the code repo. This is because our FGD needs to be in this bin folder to function, and it saves users having to copy it over. Additionally when making entity changes two seperate PRs had to be made (very annoying)
For unity lights.rad and detail.vbsp were also moved.

This removes the bin folder exclusion from the gitignore, PLEASE can the reviewers check if anything is missed by doing this and needs to be added to the ignore

As I am not as familiar with Hammer these days, and there was a mention that a tutorial draft was pending on this review... I wonder if one way to review this PR is to draft the tutorial on a WYSIWYG page like in Google Docs, and then have the reviewers work through the tutorial.

With this implemented there is no need for a Rebuild specific hammer setup tutorial- you should be able to just start the program and it'll all work out of the box. The tutorial I mentioned was for internal map compilation which I just went through with anyway, which assumes it works out of the box. You should be able to just follow the VDC guides and it'll work
