Encodeing via CLI with special characters requires characters to be escaped

[simonbbrown]

Hi!

Great little plugin, found that if I am trying to encrypt a variable that has special characters that I need to escape the characters in the string other wise the encoding will fail.

example:

FAILS:
sls encrypt -n dbep:password -v DxY5R&$a -k 1111111-2222-3333-4444-555555555555 --aws-profile mylocalprofilename

PASSES AND ENCODES CORRECTLY:
sls encrypt -n dbep:password -v DxY5R&$a -k 1111111-2222-3333-4444-555555555555 --aws-profile mylocalprofilename

If you don't escape your characters the plugin with throw the following error:
[1] 57648 bash: -k: command not found
and none of your variables will come through successfully. The function will also hang and not end correctly requiring the user to ctrl+c to halt the operation.

Would be great if documentation could be updated but also hanging issue resolved with warning in CLI?
