fragment | Implement better autocmd management | refactor

add a all_buffers option - colorizer will activate on all buffers, empty or not, still respect filetypes option

handle errors when detach is called multiple times from the same buffer

use bufdelete and bufdelete to remove the autocmds

use a more efficient compile parse_fn function

use custom ldoc template to generate vim help

+USE WITH COMMANDS                                          *colorizer-commands*
+
+   *:ColorizerAttachToBuffer*
+
+       Attach to the current buffer and start highlighting with the settings as
+       specified in setup (or the defaults).
+
+       If the buffer was already attached(i.e. being highlighted), the
+       settings will be reloaded with the ones from setup.
+       This is useful for reloading settings for just one buffer.
+
+   *:ColorizerDetachFromBuffer*
+
+       Stop highlighting the current buffer (detach).
+
+   *:ColorizerReloadAllBuffers*
+
+       Reload all buffers that are being highlighted currently.
+       Shortcut for ColorizerAttachToBuffer on every buffer.
+
+   *:ColorizerToggle*
+       Toggle highlighting of the current buffer.
+
+USE WITH LUA
+
+       All options that can be passed to user_default_options in `setup`
+       can be passed here. Can be empty too.
+       `0` is the buffer number here
