Moved CharResponseWrapper to the 'brjs-servlet' project in preparation
for re-adding the JNDI token filter, which requires this class.
Re-added the classes necesarry for the TokenisingServletFilter into the
'brjs-servlet' project, but disabled the log lines since logging
previously relied on the BRJS model, which is no longer available.
Merge branch 're-add-jndi-token-filtering-support' into re-enable-jndi-token-filtering

Changed BRJSServletFilter to be a composite filter that proxies through
to both BRJSHeaderFilter (previously called BRJSServletFilter) and the
TokenisingServletFilter.
Removed the 'logicalRequestUri' attribute since it's no longer needed.
