Improve support for CPT and CTT

[bredecl]

Hi
I made some improvements for the bones cli and content

• Added support to ask yes or no and returns a string to be used directly in stubs
• Better code for CPT, so now generates automatically the default name, plural, slug based on name
• Added a function to avoid create a post_type name larger than 20 characters (as described here: https://developer.wordpress.org/reference/functions/register_post_type/ )
• Added support to set showInRest and showUI directly supports in CPT
• Added a default icon for the stub of CPT, so we avoid the empty space
• fix to avoid loop the menu -> items when is empty
• Added support to show an example on ask method
• Added support to pre-fill the data on CTT
• Allow multiple Post Type support to CTT
• Added support to set showui by default on CTT
• Added support to manage CPT trash event.

@gfazioli I deleted it, it wasn't working as I expected, but I will work it again in it.
