* 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
* Some game enums moved to utils/enums. Others can eventually be moved there as well.
* findEnumMember function for performing fuzzy matching of player input with enum members, without needing separate fuzzy functions for every enum.
* Also used findEnumMember for safely loading save games (allows case changes in enum values)
* Changed capitalization on some enums.
* BREAKING: removed classGains work formulas function
* Split ClassType enum into UniversityClassType and GymType.
* Added universityGains and gymGains work formulas functions
* Provided the new split enums to the player on ns.enums.
Currently, the HTML line break sequence `<br /><br />` is hardcoded into the dialog box message when showing the content of these file types: ".js", ".script", and ".txt". By default, the function `dialogBoxCreate()` currently assumes that its first parameter is not HTML, but a text string, so whatever is in the string will appear in the dialog box. Use the newline character instead for line break.
* purchasedByPlayer allows connect-from-anywhere as if the server was backdoored.
* Also added optional backdoorInstalled variable to type for BaseServer. This has no runtime effect, but it allows accessing that variable without TS needing us to verify whether it's instanceof Server first.
1MB added to available ram when checking if available is sufficient. All actual ram values in game are a multiple of 50MB so an extra 1MB can't ever allow additional script load to be ran.
