Allow display of Java program logging

[bgaillard]

When the server starts it displays several logs and redirects them into a log file. It works but it does not allow a developer to quickly know what's going on.

Here are sample logs.

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

We should be able to display those logs and categorize them (download, mongo start, etc...).
