[PATCH 03/11] Fix token-related command line options

[Kevin Cernekee]

Aliasing --stoken to --token-secret is not effective because token_mode
does not get set.  Might as well just drop --stoken.

For --token-mode, change "stoken" to "rsa" to make the UI more intuitive:
liboath provides TOTP token support, and libstoken provides RSA token
support.
