kirc requires a proper text editor

[mcpcpc]

Using fgets() to read user input from the stdin buffer is a fragile solution that required proper handling on the VTE-end. This impacts the portability as implementation of terminfo flags varies and is not guaranteed. Going forward, we need a solution that has fewer dependencies on the actual VTE.

Considerations...

• Do nothing. Set VTE flags via escape command sequences. Reduces portability as user experience may vary from terminal emulator to terminal emulator.
• Restrict input char length. This probably the easiest solution, but really hinders the project and user experience.
• Create a custom text editor. This will quickly increase the size of kirc and adds unwanted complexity.
• Bring your own editor (BYOE)! This probably my favorite concept but possibly adds significant complexity to how kirc interacts with external editors.
