Subject: [PATCH] Adding support for alfanumeric index access

You can have alfanumeric keys together with numeric keys. I changed the regular expression to fix this.

Example:
```
var arrResults = {"ID4":{"MAXNUMBERPRATICA":"27652","_odbc_connection_id":"ID4"},"4":{"MAXNUMBERPRATICA":"123456","_odbc_connection_id":"ID4"}};
console.log(sprintf("check results = %(arrResults[4].MAXNUMBERPRATICA)s",{"arrResults":arrResults}));
console.log(sprintf("check results = %(arrResults[ID4].MAXNUMBERPRATICA)s",{"arrResults":arrResults}));
```
