Fixes in the release:

• Some makefile updates.
• Handle when someone tries to send an empty string.

New feature! You can change your nick.

• Fixed some sketchy memory handling with (probably) more sketchy memory handling.
• Makefile should be better behaved now.
• Some (hopeful) fixes for OpenBSD.

getlogin wasn't being reliable, so per the manpage:

For most purposes, it is more useful to use the environment variable
LOGNAME to find out who the user is. This is more flexible precisely
because the user can set LOGNAME arbitrarily.

• Added a comment in the man page regarding security issues.
• Updated versions and copyrights and etc.

• Added manual page.

• Fix the error message when an invalid slash command is given.
• General housekeeping of the code.
• Fixed some README stuff and added a demo gif.

• Added README with some instruction for the project.
• Add installation target to makefile.
• Remove need for signals/timers.
• Print a message regarding unknown slash commands instead of sending them as a chat.
• Clean up the prompt area before exiting.
• Some internal housekeeping, refactoring.
• Ding when the current user's nick is mentioned in the chat.
• Fix a performance issue where CPU is bound at 100%.

• Fix makefile for compilation.
• Remove possible buffer overflow.

Features currently available:

• Inherent logging of all messages (just cat/grep the file)
• Timestamp and nick of user along with message.

I look forward to feedback!
