Vim: O and o should respect/understand current context (lists)

For fellow vimrc noobs / lazy people such as myself, the fix for 1.7.4 (removed the 2 intermediate mappings as well):

  exmap blankBelow obcommand obsidian-editor-shortcuts:insertLineBelow
  exmap blankAbove obcommand obsidian-editor-shortcuts:insertLineAbove
  nmap o :blankBelow<CR>i
  nmap O :blankAbove<CR>i
