Several bug fixes and improvements for `/root/.zshrc`

While debugging #30 I noticed that root's zsh leaks red foreground and doesn't understand comments:

Here the first 3 red lines is the command I've typed. export LESS=-r is the output of tail. Note that both of these are red. And then there is "bad pattern" error due to a comment in my command.

Also, my Home and End keys didn't work. I've fixed these issues and a few more that I noticed in the same file.

• Don't leave red foreground on at the start of every command. This causes the command line to be red. It also randomly and inconsistently colors output of commands red.
• Remove an unnecessary space from right prompt.
• Use the newer syntax for colors: '%F{red}this is red%f'.
• Show '%' instead of '#' in prompt if the user is not privileged. This matches bash prompt (although bash uses '$' instead of '%') and standard convention.
• Correctly autoload functions even if KSH_AUTOLOAD is set.
• Make Home and End keys work in all mainstream terminals.
• Remove '/', '&', '.' and ';' from WORDCHARS as it seems to have been intended. Previously, only '/' and '&' were removed.
• Enable INTERACTIVE_COMMENTS so that zsh doesn't barf when users copy-paste commands with comments in them.
• Replace APPEND_HISTORY with INC_APPEND_HISTORY. The latter is significantly less likely to result in the loss of history and it matches the existing comment.
