Describe

Upgrade shellcheck version to v0.7.1 from 0.4.1 so users can get the warning wiki URL when they occured.

For example:
If we shellcheck this script,

#!/bin/sh
## Example: a typical script with several problems
for f in $(ls *.m3u)
do
  grep -qi hq.*mp3 $f \
    && echo -e 'Playlist $f contains a HQ file in mp3 format'
done

shellcheck will generate these:

In test.sh line 3:
for f in $(ls *.m3u)
         ^---------^ SC2045: Iterating over ls output is fragile. Use globs.
              ^-- SC2035: Use ./*glob* or -- *glob* so names with dashes won't become options.


In test.sh line 5:
  grep -qi hq.*mp3 $f \
           ^-----^ SC2062: Quote the grep pattern so the shell won't interpret it.
                   ^-- SC2086: Double quote to prevent globbing and word splitting.

Did you mean:
  grep -qi hq.*mp3 "$f" \


In test.sh line 6:
    && echo -e 'Playlist $f contains a HQ file in mp3 format'
            ^-- SC2039: In POSIX sh, echo flags are undefined.
               ^-- SC2016: Expressions don't expand in single quotes, use double quotes for that.
