Feature/0.17apiv2

[Roang-zero1]

I took the release of 0.18 as a call to arms to finish my work on #53 ! I went through the history and cherry-picked the applicable code parts.

So here is a list of features currently available:

• Tracking of status with the 0.17 entity-status API
• Flexible settings and entity initialisation to allow easy extension and avoid breaking when a new status is added to the API
• New icon from feather icons (also under the MIT licence)
• Support for rocket silo
• Small fixes to existing functionality (labs are working again xD)

Still open

• [x] Attribution to feather icons
• [x] Translations for the new settings
• [ ] Tests by someone other than me, preferably on a megabase

What has been left behind:

• Rendering the signals as sprites (still not as fast at sing entities)
• The bottleneck toggle in the shortcuts (entities are force display not player specific)

What could be salvaged:

• The thumbnail: https://github.com/Roang-zero1/Bottleneck/blob/feat-0.17api/thumbnail.png (please give feedback on this one)

Updated pull request description

This pull request supersedes #46 as the API now provides this functionality from within the base game,

Great work! I'll have some time to test it later today. The icon looks perfect.
