"with" statement compatibility issues on ESAPI.js

[enrico-usai]

In row 533 of ESAPI.js there is:
with(org.owasp.esapi.Logger) {
that causes some problems in Firefox, because the org.owasp.esapi.Logger.ALL and other Logger constants result undefined.

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/with
Use of the with statement is not recommended, as it may be the source of confusing bugs and compatibility issues.

Tested with Firefox 50.0.1 (Windows)
