Add log setting filter in Share Log4J Settings

[AFaust]

FEATURE / ENHANCEMENT

The Log4J Settings tool within the Share UI currently allows filtering of loggers based on name patterns and the distinction between "has explicit setting" vs. "inherits setting from parent". It might be a usefull enhancement to either add an additional filter for specific log settings or incorporate this with the existing filter for explicit/inherited setting. In the latter case the values could be the potential log levels combined with a set of meta- values, e.g. "All", "All unconfigured", "All configured".
