There was a tab instead of spaces

I made an error in previous fix

#7504 integration has missed this part.
When more than 1 servo is used with bltouch it's impossible to predefine default servo delay for it.
In my original fix I completely removed this part but maybe this is a better compromise

This modify give SERVO_DELAY x servo basis

Based on patch by Kelly Anderson <kelly@xilka.com> at

20x4 map integration.    Also some minor changes to the UBL Menu layout.     Both 20x4 LCD's and Graphical LCD panels should have similar functionality now.

Add support for the PCA9632 PWM color LED driver used on the Ultimaker 2 and Wanhao Duplicator 6.

* Save up to 94 bytes of RAM on 20x4 LCD Display machines

Moved the custom screen characters out of RAM into Program Memory.  With
SD-Card support and the Progress Bar enabled, this saves 94 bytes of RAM
memory.

This was tested using the example_configurations/FolgerTech-i3-2020
files.  So a couple small changes to those files snuck into this Pull
Request.

Probably...  We can find similar savings in the Graphics LCD code it we
comb through it.   And if so...  That is the place we really need to
save RAM memory!

* Tidy up white space and indentation

Plus some other UBL tweaks.

The OLED is driven by an SSD1306, connected to the board via
I2C, the rotary encoder is connected to 3 GPIO pins.

Rather than include twice, which is tricky but may confuse
