This improves the term extension in a few ways.
First it fixes some vint warnings about case sensitive comparisons.
Next it makes the active and inactive variants consistent, as well as
making the line number display consistent to other buffer types. This
was one of the main reasons to do this, because the inclusion of the
Neoterm ID in a previous pull request made inactive terminal status
lines look really inconsistent compared to the active ones.
Further this now shows the Neoterm ID in both active and inactive
buffers in Airline section B. It also removes the now redundant
Neoterm IDs from the buffer name in both Neovim and Vim.
Finally the cosmetic buffer name is now used for both active and
inactive variants.

- Make sure to always call the term extension on TermOpen autocommands
- consistently use the airline_term highlighting group
- hard code the airline_term highlighting group, because by the time the
function airline#themes#patch() is called the highlighting group
airline_c would no be defined, so we cannot dynamically get those
attributes
- In the documentation, mention how the g:airline_mode_map can be set
including the terminal section
