custom text stats enhance

[amigthea]

It would be really useful to be able to configure multiple custom_text= and exec= pairs, along with a custom_text_size= and custom_text_color= options.

amazing project btw <3

also multiple exec value for the same custom_text, like usage and temperature are for cpu and gpu stats. To give an example, I have a ups connected by usb to my desktop pc and would like to show both power usage and battery percentage. I cannot currently do this with integrated battery stats because usb connected ups are not recognized by kernel as /sys/class/power_supply device.

ps: this scenario would need also a custom small text to show watt and percentage symbols next to each exec values
