[Fix] `nvm use`: fix `--silent` when version is omitted Fixed a bug where --silent mode was failing for nvm use I ran a test that just ran ```nvm use node --silent``` that I wrote by myself. Unfortunately I noticed a bug where it still prints out some messages in different cases. This pull request is to fix that bug. * Added in an argument called *quiet* to the nvm_rc_version() function at line 339 * Printed anything inside the nvm_rc_version() only in the scenario where quiet mode is off * Ran the nvm_rc_version() function in quiet mode only if silent mode is on in the "use" command of nvm at line 2990 * Ran nvm_echo and nvm_err inside the "use" command of nvm only in the scenario where silent mode is off (There were 4 scenarios where this was forgotten) * Edited the ```nvm deactivate``` command to include a silent mode * Changed the help page to include the --silent option for ```nvm deactivate``` * Added in aliases for the --silent flag in ```nvm deactivate``` and ```nvm use``` * Used silent mode inside the ```nvm use``` when running ```nvm deactivate``` inside it and silent mode is on A test was attached in the 'test/slow/nvm use' directory. It is named Running "nvm use node --silent" doesn't print anything. It runs ```nvm use node --silent and checks``` and succeeds if the OUTPUT matches the EXPECTED_OUTPUT which is null or ''. When the test was run locally, it still ouputed results if someone deleted some contents of the .nvm/ folder. This output was given from the ```nvm deactivate command```. This was the reason that the ```nvm deactivate``` was edited to include silent mode. 2020-08-09 08:27:46 +08:00			`#!/bin/sh`
