Make Filament tab easier to use -- UI/Feature request

[Darkknight33]

Is your feature request related to a problem? Please describe.
When using the Filaments tab the drop down box to select filaments is a slow way of accessing all the different filament profiles.

Describe the solution you'd like
On the right side of the UI on the Filaments tab, a section on the righht that lists all the available filament presets sorted by printer would make viewing and accessing the filament profiles so much easier. Additionally, move the 'Notes' text box into the 'Filament' left menu item so it displays right away when clicking on a filament profile, rather than putting it under a separate menu item.

Describe how it would work
You implement a section on the right, in that column, all the filament presets would be visible. By default, all presets would display, with filament profiles below the printer they are attached to. Ideally, you'd have some filtering options at the top to filter by material, cost, color, temps, etc.

Describe alternatives you've considered
None

Additional context
Right now the filament profiles are on visible in the drop down box only for the physical printer selected. If implemented the way I'm proposing, all the filament profiles would be displayed -- which I think is a better way of displaying it. I'm even thinking that maybe it'd be better to reconsider how filaments are implemented in Slic3r such that instead of a printer having different filament profiles, the filament profiles exist independently, and different printer tabs under the filament tab are available for each printer's filament settings. I believe this is more representative of how filaments are used, since one roll may be used with multiple printers. So you'd make settings on that roll, rather than creating duplicate and complicated profiles for each printer you are using. Right now, if you are trying to keep track of weight, it's difficult to do if you use it on different printers since each printer has it's own filament profile.
