Convert all string references from const char* to String/F() to store values in flash instead of ram.

Memory usage from main:

Sketch uses 27878 bytes (90%) of program storage space. Maximum is 30720 bytes.
Global variables use 1755 bytes (85%) of dynamic memory, leaving 293 bytes for local variables. Maximum is 2048 bytes.

Memory usage after these changes:

Sketch uses 28054 bytes (91%) of program storage space. Maximum is 30720 bytes.
Global variables use 1445 bytes (70%) of dynamic memory, leaving 603 bytes for local variables. Maximum is 2048 bytes.

This provides a dynamic memory savings of 310 bytes!
