V1.2 Beta Release

Alright, so I've made some changes to the software. My goal was to make it easier to use for non-technical users. Here's the changelog so far:

• Only three fonts are available now. Comic Sans was causing problems.

• Completely rewrote GUI and GUI functionality. Now you can only select/access public keys.

• The private key is stored in the preferences file now. No more risk of accidentally sending over your private key!

• Public Key button text changed slightly for understanding.

• Warning box now displayed when the user tries to save a file as plaintext.

• Creates a directory named "Keys" if it doesn't exist already. This is where your public key will be stored, too!

• Dialogue box prompts the user if they want to keep the same codename when creating keys (if they have a codename already).

• When entering in a codename, a blank answer will result in the user being asked to put in a proper codename.

• The manual now elaborates on the reason for the plaintext saving option existing in the first place.

The pictures in the manual are somewhat old, so don't refer back to it too much. The text is updated, though.

Hope this is more widely usable!

Also, there is a known bug where if you don't have a valid codename and the config file exists, the software won't run. I'll work on this later.
