Collect game info

[HenryQuan]

Once we no longer rely on the official API, we will be collecting game data ourselves. The entire process should be automated, no manual parsing unless required.

Data we need:

• Achievements
• Collections
• Upgrades
• Flags
• Camouflages
• Commander skills
• Ships
• Maps

Ships also contain modules, and their information should also be retreived.

The current json file is around 6 MB. I will be testing it on my iPhone SE and make sure it is acceptable. On my old SD835 phone, it takes about 1.3 sec. This shouldn't be a big problem I hope...
