* Added new types for various file paths, all in the Paths folder.
* TypeSafety and other helper functions related to these types
* Added basic globbing support with * and ?. Currently only implemented for Script/Text, on nano and download terminal commands
* Enforcing the new types throughout the codebase, plus whatever rewrites happened along the way
* Server.textFiles is now a map
* TextFile no longer uses a fn property, now it is filename
* Added a shared ContentFile interface for shared functionality between TextFile and Script.
* related to ContentFile change above, the player is now allowed to move a text file to a script file and vice versa.
* File paths no longer conditionally start with slashes, and all directory names other than root have ending slashes. The player is still able to provide paths starting with / but this now indicates that the player is specifying an absolute path instead of one relative to root.
* Singularized the MessageFilename and LiteratureName enums
* Because they now only accept correct types, server.writeToXFile functions now always succeed (the only reasons they could fail before were invalid filepath).
* Fix several issues with tab completion, which included pretty much a complete rewrite
* Changed the autocomplete display options so there's less chance it clips outside the display area.
* Turned CompletedProgramName into an enum.
* Got rid of programsMetadata, and programs and DarkWebItems are now initialized immediately instead of relying on initializers called from the engine.
* For any executable (program, cct, or script file) pathing can be used directly to execute without using the run command (previously the command had to start with ./ and it wasn't actually using pathing).
`args[numArgs - 1]` is the last argument in the list, so correct usage was being flagged as incorrect, and incorrect usage wasn't working anyway because the filter was `"undefined"`.
Additionally, the function seemed confused as to whether or not `ls` counted as an argument (AFAICT, it isn't).
Fixes#1994.
