Issues after pull request #30

[ikarus23]

Hi! Thanks for the great project!

After the #30 there are some issues with the setup.

• Choosing the "ESP32 Dev Module" board results in pins (like LED) being undefined. The pin definitions were moved from defines.h to plattformio.ini But I use the the Arduino IDE (old version). Also, the note in defines.h says "move to defines in platformio.ini". I guess this should mean "moved" and is not an instruction to move C code to the plattfromio.ini
• The added SPIFFSEditor.cpp and SPIFFSEditor.h results in a conflict (using the Arduino IDE). The files are already specified in the ESPAsyncWebServer library.

Using da52f00 still works the way described in the readme. Deleting the new SPIFFSEditor files and uncommenting the pin defines in the header also works.
