Small improvements.

- funded and fish_indent always uses tabs for indentation, use
  fish#Indent() to fix it. Works better with the improved fish#Indent().
- ftdetect should contain filetype detection code. Move autocmds to
  plugin/fish.vim.
- Match new funced temp file name.
- Add "else", "else if" and "case" to b:match_words to follow what's
  used by Vim's ftplugins.
- Use "syn sync fromstart" for a more accurate highlighting.
