Development branch for Text Editor

Going to replace notepad, fix encoding problem, and make LockNut more
portable.
Create file uses Editor
Create File Reorganized

Shift over to internal editor is going smoothly. Create file is almost
entirely in LockNut now. Encrypt/Decrypt and Glance will need
read-canvas and editor canvas in Encrypt.rkt.
Glance Editor

Glance Editor added. Thinking of removing Encyrpt/Decrypt entirely and
having the functionality be absorbed by Create and Glance
Major Restructuring

In progress:
Glance
+ Re encrypt file

Create file
+ Load file

- Encrypt/Decrypt
Working, with bugs

Create file and decrypt both work. Error when creating a file that
wasn't loaded.
Complete!

Everything functional again! Unencrypt has replaced Glance and now
allows editing & reencryption, and saving to plain text.
Cleaning
