* DOC: Move all docs into en/ subdirectory
PR #1502 is working on adding a Chinese translation to the docs. In
general, I encouraged this (in #1452) as a path towards getting useful
translated content in the game without requiring a massive
refactor/rearchitecting of everything.
To support this, this takes the first step of moving our docs into an
en/ subdirectory, so that other languages can live alongside. No effort
is made at this time to support or select between alternate languages;
this is a pure-rename refactor.
Changed SF1 to apply a 1/incMult multiplier to hacknet costs to match how NFG, SF12, etc. handle it. Previously was calculated as a %reduction.
Changed wording on SF9 to include a %reduction in hacknet costs.
Buffed SF9 effect to 12% base from 8%, to make up for weaker hacknet cost mults from SF1.
* Added new positive integer ns validation helper
* `run`, `exec`, and `spawn` verify threads as a positive integer.
* `run` terminal command also fails if the provided threadcount is not a positive integer.
* Removed some references to .script files in various documentation, and removed some of the NS1 example blocks
* handle enums differently
* Enums are frozen and fed directly to the proxy
* Enums are not included in the NSFull definition, allowing samekeys for RamCostTree<API>, InternalAPI<API>, and ExternalAPI<API>
* Rewrote a lot of the ramcalc test, with better typing thanks to the samekeys above
* Fix ns1 for proxy (args, pid, and enums after above changes were not being added to ns1 scripts.)
* Fixed an overview issue where the bars could display inaccurately.
Update changelog and bump version to 2.2.1
