Customize numeric field edit cursors

[neu-rah]

as asked by @lamqhoang at gitter channel

Can I set the FIELD menu indicator instead of the default ":" and ">"

this is quite easy to do and no impact on library size, at this moment the fieldBase class is printing the cursors hard coded, they can however be turned into static fieldBase members and possibly using strings instead of characters (to allow UTF8 stuff)

field cursors are being printed here: https://github.com/neu-rah/ArduinoMenu/blob/master/src/items.cpp#L365

Hi neu-rah, I've implemented it the way you suggested it:
