API Changes:
Adds ns.gang.getRecruitsAvailable: Gets the number of additional gang members that can currently be recruited
Adds ns.gang.respectForNextRecruit: Gets the respect threshold for recruiting the next gang member
Adds ns.gang.renameMember: Renames a gang member
Plus many doc and ui improvements
* Add specific types for sleeve tasks
* Moved LocationName enum to overall enums file
* Add LocationName enum to those provided to player
* remove trailing s on CompanyPosNames enum (now CompanyPosName, in line with LocationName)
* Also regenerated all ns documentation. This leads to an expected error when checking for generated files, because PRs should not normally touch markdown files. Also leads to a lint failure in generated file bitburner.d.ts
* also removed some exporting from NetscriptDefinitions.d.ts for anything that wasn't imported somewhere else.
