Adding Power Play functions to the BGSBot

[OttoVonGrim]

At the most basic level, a function that lists the populated systems less than 15.00LY from specified system, including the specified system.

Additionally, provide the ruling faction name and it's government type for each system listed.

Bonus extras, provide the following additional details:

• PP status of each system (control, exploited, contested) and which PP factions are involved (e.g. contested by Yuri Grom and Denton Patreus
• population of each system, or even better the CC value of the systems based on their population levels

Currently I am not storing any powerplay related data, although I had initially planned that but my extremely limited knowledge of PP is somewhat preventing me from including powerplay in EliteBGS API (which BGSBot is based on). PP might happen someday but that API needs station data first.

Population data is present along with system government and it can be put on the systemdetail.

CC value is not present in the journals supplied by FDev and I don't know how else I can get that.

Ruling Faction name is already present.

And I believe I can add that systems within a distance command. Keep checking this issue.
