0897ab7092 Add handling for special characters in parameter substitutions. 
Fixes koalaman/shellcheck#562. Special characters inside braces are
parsed into T_ParamSubSpecialChar instead of T_Literal so that they are
not flagged in the function checkInexplicablyUnquoted when sandwiched
between double quotes.

eaa319ec57 Emit the end line in the JSON. 
This handles the case where the end line is not on the same line as the
start line when using the new end column feature.

7f5f5b7fb5 Make SC1035 emit a proper end column 
Example JSON output:
```
$ shellcheck -s bash -f json /dev/stdin <<< "[[0 -eq 1 ]]"
[{"file":"/tmp/zshNCNwPz","line":1,"column":1,"endColumn":3,"level":"error","code":1035,"message":"You need a space after the [[ and before the ]]."}]
```

856d57f7d8 PositionedComment and ParseNote contains end cols. 
This change makes PositionedComment and ParseNote contain end columns.
It additionally modifies the JSON formatter to show the end column in an
"endColumn" property. No modifications to the messages shown by any
other formatter have been made.

Currently, all checks set the end column to the start column. It should
now be possible however to start setting the end column in the parser.
Additional work is needed to set the end column during AST analysis.
