QuecManager 1.0.2 BETA

- Added signal graphs for RSRP, RSRQ, and SINR
- Added ethernet connection details
- Added memory usage details
- Added ping graph

Known bug:
Signal graphs may sometimes show inaccurate values. It seems to be a fetching error but Ill try to find the real root cause as soon as possible
