message:
SC2034: $VARNAME appears unused. Verify it or export it.
most of these are related to the style:
we generate global vars, which are used in other functions.
the var "lexical_url" was really unused (left it as comment)
the travis-check now does not need anymore special flags.

1. Unix-like command api
2. 100% compatible with le.sh 1.x command api.
3. Support different webroot for each domain in the same cert.
```
le.sh --issue -d a.com -w /wwwroot/a.com -d b.com -w /wwwroot/b.com
```
4. Support different authentication methods for each domain in the same cert. Hybrid usage:
```
le.sh --issue -d a.com -w /wwwroot/a.com -d b.com -dns dns-cf
```
