Adds maxLength support to TextEdit, then also consitently displays message for LineEdit. Should be ready to merge from my side

BTW. is modal bool of DisplayMessage supposed to do something different? I tested with true/false and noticed 0 difference for non-question messages at least.

Visually they are the same.
They only differ in how they behave in regards to the interaction with other windows of the same application.

To be concrete, modal dialogs will prevent you from interacting with other windows of the application, until they are closed, while non-modal dialogs do not.

For example, the advanced scene switcher plugin's settings window is a non-modal dialog window as it still allows you to interact with OBS while the dialog window is open.

Hope that clears things up! :)
