Add additional logos for Japanese networks

[althonos]

This PR adds logos for several Japanese animation networks. I used the nomenclature from TheTVDB. Images come from Wikipedia and were resized / lightened.

Here are the new logos:

• ABC (JA)
• BS11
• CBC (JP)
• CTC (JA)
• FUNimation Channel and FUNimation Entertainment
• Nippon Columbia
• Nippon TV
• Sky PerfecTV!
• TokyoMX

I also redid the NHK logo because the sides were cropped and the inner lines for the N/H/K letters didn't look very good at small resolution.
