Added @fzf-url-open (#36)

* feature: added the setting 'custom_open' to specify a program to open the url/file. Can be used when xdg-open/open are installed but the user does not want to use them.

* refactor: moved $custom_open inside of open_url function

* docs: added fzf-url-open to the README.

* bugfix: added quotes around custom_open

 set -g @fzf-url-fzf-options '-w 50% -h 50% --multi -0 --no-preview --no-border'
 ```
 
+By default, `tmux-fzf-url` will use `xdg-open`, `open`, or the `BROWSER`
+environment variable to open the url, respectively. If you want to use a
+different command, you can set `@fzf-url-open` to the command you want to use.

+```tmux
+set -g @fzf-url-open "firefox"
+```

 ### 💡 Tips
 
 - You can mark multiple urls and open them at once.
