* Convert purchased server functions to cloud API
- Create `ns.cloud`
- Change `bitnode multipliers` and `server constants` wording for consistency
- change `server`, `ram` and `getting started` docs for consistency
- Added changes to 3.0.0 API Break and `setRemovedFunctions` in NetscriptFunctions.js
Tested by
- running tutorial `purchase-server-8gb.js`, and a more typical player one
- buying manually using vendor (Alpha Ent in Sector 12)
- deleting them all using script, and checked all deleted functions gave correct error
- Imported completed save to ensure auto-transfer of function work
* Revision in line with comments
- changed more `purchased` to `cloud` references
- Added BN mults auto-conversion
* Update getting_started.md
