When using Neovim and switching to another buffer with the mouse and the
current buffer is modified, Vim refuses to switch buffers rightfully,
if the user has not set 'hidden' or 'autowrite' (because it is going to
unload the buffer from memory).
So catch this case and let the user know.
Note: :b! would be another possibility, but I do not prefer using this
attribute, because it is not clear what happens to the current buffer. I
think it is made hidden, but I prefer to be explicit here

if the same highlighting group is used on the left and right for the
label, the `airline_tablabel_to_airline_tabmod` will be overwritten on
the right side, causing the fg/bg colors to be wrong, because on the
right side they have to be the opposite of the left side.
So use a separate highlighting group for the tablabel on the right.

Partly revert commit 105e9daaf7
and fix#1857 another way, by making sure, that buffers are not taking
away from the s:current_visible_buffers list.
Fixes#1857Fixes#1872
275ec4fe63 broke this so that numbering
started from 0 instead of 1 with
g:airline#extensions#tabline#buffer_idx_mode = 1
Specifically, I overlooked that |index| actually tracked the index of
the current buffer in the buffer list *starting from 1*, whereas I
assumed it tracked the true index (starting from 0).
looks like this:
```
let a=(condition ? s:var:'')
```
confuses older Vims and it complains about a missing colon. So make
parsing a bit easier and add a space in front of the second colon.
fixes#1629
commit ab49a1c7ae changed that no leading whitespace was added.
While this removed a double space in front of the current active
selected buffer, it removed one space too much for the non-current
buffers in the bufferline.
So partly reverse it and only add the space, if the highlighting groups
between each item did not change.
previously, when both tabs and buffers were displayed in the tabline, it
was not immediately obvious which side belongs to a buffer and which one
to a tab. Therefore, add [buffers]/[tabs] labels consistently.
Adding an option to prevent windows from being closed when a buffer in
the tabline is middle clicked and the clicked buffer is currently open
in a window.
When this option is enabled, instead of closing the window a new buffer
will be opened in all of the windows editing the clicked buffer instead.
This is my first pull request AND my first experience with vimscript, so
my apologies if this is a bit sloppy 😄
