Jannik Beyerstedt 65fc825250 [FIX] Schematics: Revised values and PCB errata text
* fixed trim pot range at VU meter
* TODOs removed (5V V_LED didn't work out, 10uF at LM386 wasn't better, VU meter filtering not needed)
* phantom power voltage changed and readme chapter added
* hardware errata: gain pot. pins are swapped, ground plane isn't fully connected

Footprints and PCB aren't fixed to keep the schematic compatible with the existing PCBs!
