Knightly 7ab909ee47 Standardize Licensing
- License was intended to be GPLv3 per earlier commit of GPLv3 LICENSE FILE
- This is confirmed by the inclusion of libraries that are incompatible with GPLv2
- This is also confirmed by KLS and the agreement of KLS's predecessors
- Added GPLv3 license headers to the compilable source files
- Removed Folly licensing in strings.h since the string functions do not match the Folly functions and are standard functions - this must have been left over from previous implementations
- Removed individual contributor license headers since the project has been under the "developer" mantle for many years
- Removed comments on files that were previously automatically generated since they've been manually modified multiple times and there are no automatic scripts referencing them (removed in 2023)
