Refactored bb +... to bbcmd ... within bb bindings. This makes
things a lot less ambiguous. Also removed the default marks created in bbstartup.sh and ensured that `$XDG_DATA_HOME` and `$XDG_CONFIG_HOME` always get set as environment variables.

Internally, `bb` writes the commands (NUL terminated) to a file whose path is

be passed to bb at startup, and will run immediately. E.g. `bb '+col:n'

### API
|
||||
|
||||
`bb` also exposes an API that allows shell scripts to modify `bb`'s internal
|
||||
state. To do this, call `bb +<your command>` from within `bb`. For example, by
|
||||
default, `j` is bound to `bb +move:+1`, which has the effect of moving `bb`'s
|
||||
state. To do this, call `bbcmd <your command>` from within `bb`. For example, by
|
||||
default, `j` is bound to `bbcmd move:+1`, which has the effect of moving `bb`'s
|
||||
cursor down one item. More details about the API can be found in [the API
|
||||
documentation](API.md).
