Feature request: Ability to open the Logs folder in Windows Explorer (VSIX-49)

[BenedekFarkas]

When there are no unseen additions in the error log (i.e. the red dot indicator is inactive), clicking the Orchard icon could open the file explorer in the Logs folder.

I briefly look into this and it's not as simple as I thought. We need the following:

• A new icon for the button's enabled but not "new log entry" state (there is an Orchard logo icon in the app but it's grey-ish, not green as the base or the icon with the red dot).
• Change icons on the fly. OpenErrorLogCommand currently only enables/disables itself to change state but it'd need to change icons as well. However, this is not possible and instead we'll need to use two commands and swap their visibility.
• Somehow manage the states apart from the log file not existing and having been updated, also that it can simply exist or not and how this changes. The good news is that ILogFileWatchers already handle this and OpenErrorLogCommand.LogFileUpdatedCallback() will be called when a new log file is created but it's empty.
