New Version Beta 0.2.1

After the feedback received the first changes and a new version beta 0.2.1

Changelog

• Added "Resume" in the Menu. Some users complained that for their system it could happen that the game would freeze progress without crashing. That might have been due to the pause during discussion that was not resumed. The current system for pause/resume is delicate and might depend on framerate and runtime. This is a hotfix that should allow to recover the game. I hope is visible enough.
• Added a power signaler that shows the much-contested power fluctuation. Hopefully this visual queue, together with a more explicit dialog, should help avoid confusion.
• Fixed a little bug regarding the construction of drones that was not taking energy.
