* Add support for enums at other ns layers
* APIWrapper: simplified wrapping algorithm and modified to just use cloneDeep to copy enums instead of recursively wrapping enums as if they were new API layers
* Improve APIWrapper typing
* Changed some typings at RamCostGenerator to allow for enums at different levels without enums needing a ram cost
* Added enums to ns.corporation, removed getter functions that were being used instead.
* Add FactionWorkType for player use
* Add ClassType and CompanyWorkPos enums
* Change netscriptDefinitions to expect members of these new enums where appropriate.
Reverted ToastVariant back to an enum internally. Still exposed to player as just possible strings.
Changed all 1-line documentation comments to actually be 1-line. Moved some because they were not providing documentation for the thing they were trying to.
Saved scripts is stored on servers with its starting & trailing whitespace removed, so
comparison would fail and show the file as dirty when there was a
trailing newline in the script.
Found most (hopefully all) places where the error message wording
incorrectly was shown to the tune of 'no script exists', where it should
have been showing to the effect of 'script is not running'.
Also cleaned up some of the consistency in the wording and added a
'helper' export for knowing valid script extensions used in validation
of 'isScriptFilename', so we can have consistent error messaging.
