Haskell stuff
Use Django template syntax for Swig views
Add arduino to filetypes with C-style comments
Use echom instead of echo for messages
Add setting to automatically detect indentation when loading a file

This is necessary because the autocmd must be set before custom filetype
plugins are loaded.  Otherwise, a file can be opened which should
receive a filetype that has C-style comments, but detectindent will not
know about the filetype yet, so it will not be marked as having C-style
comments, which could result in incorrect indentation being detected.
Change detectindent settings
Remove <Leader>a mapping since it will be used for Arduino
