Placeholder for features being temporarily removed

[timmbogner]

Both the logging and the debugConfig features have been broken due to various changes I've made, but I want to fix them up again.

Right now I'm trying to work through the readme files and update everything, and I want to remove documentation and config references to these without removing the code.

@thefeiter SD logging is doing unexpected things, and FS logging is showing an error when it initializes. There's a big future for logging functionality in FDRS once timekeeping is finished!

@Gulpman debugConfig was disabled when it conflicted with something (I forget), then when I added OLED support I decided I wanted to reformat it to look good on a small screen. That is on my to-do list as part of a larger revisit to the OLED functions, but I figured I'd ping you about it in case you have input.

I'm cut/pasting the documentation entries below for future reference.

#define DEBUG_CONFIG

This displays a readout of the device's configuration on start-up.

Thanks to @gulpman for this feature!

#define USE_SD_LOG, #define USE_FS_LOG

Enables SD-card logging. Used only on the MQTT gateway if sending the MQTT message fails. Make sure to set the correct SD_SS (chip select) pin in the lines below.

Logging is done in the following CSV Format: timestamp,reading_id,type,value

Thanks to @thefeiter for this feature!
