Document breaking changes

[ajkessel]

My code was accessing ThemeManager.theme in customtkinter. I realize this was nonstandard but was allowed/supported by customtkinter. When dropping in custom2kinter, it exposes an AttributeError. I suggest you collect "breaking changes" like this as much as possible so users who want to make the switch can identify necessary changes, i.e. anything that would prevent custom2kinter from being a drop-in replacement.

I'll keep updating this issue as I find them:

• _textbox has become _text. Although _textbox was an internal method, I suspect a large class of users was accessing that internal method because CTkTextbox didn't (and still doesn't) expose tag_configure, tag_bind, tag_names, etc. as first-class methods.
• CTkProgressBar - no longer supports width only length
• font=None - no longer supported in CTkLabel

Hi,
Consider that the next release of the library will be numbered "6.0.0" to clearly indicate that it isn't compatible with the previous one.
I've performed so many changes that I don't suggest updating existing projects. If you really want to do it, you will have to work a lot to fix all the different namings and sometimes also behaviors.
Here's my answer for the current points:

• tag_configure, tag_bind and tag_names have been added: CTkTextbox inherits from TextLike, which has those methods. Moreover, tag_configure has been improved to accept and correctly use the font parameter.
• All widgets with orientation parameter had their width and height parameters changed to length and thickness, so that you can change the orientation without having to update the dimensions too.
• How do you use font=None? Do you expect to use the default parameters?
