Disable console notification by default within the library

Browse Source 
As a library, the default shouldn't be to write anything on console.
`cover` and `fastcover` have a `g_displayLevel` variable to control this behavior.
It's now set to 0 (no display) by default.
Setting notification to a higher level should be an explicit operation by a console application.
