[PATCH v3] [NEW] eeschema: Allow hierarchy navigator to stay open

 

From: Franck Jullien <franck.jullien@xxxxxxxxx>

User can now decide to keep the hierarchy navigator open while working
on a schematic. This behavior can be configured in
eeschema->preferences->eeschema->Editing options.

Signed-off-by: Franck Jullien <franck.jullien@xxxxxxxxx>

v2: fix coding style
v3: fix memory leak after Wayne review
