to which environment variable and how they work.

Fixes #33.

The environment variables have the following effects:
```sh ```sh
BEMOJI_DB_LOCATION="$XDG_DATA_HOME/bemoji" # where the emoji lists reside BEMOJI_DB_LOCATION="$XDG_DATA_HOME/bemoji" # where the emoji lists reside
BEMOJI_HISTORY_LOCATION="$XDG_STATE_HOME" # where the state file resides BEMOJI_HISTORY_LOCATION="$XDG_STATE_HOME" # where the state file resides

BEMOJI_ECHO_NEWLINE=true # whether to end the output with a newline character BEMOJI_ECHO_NEWLINE=true # whether to end the output with a newline character
``` ```
They can either be set like `export BEMOJI_LIMIT_RECENT=5` before executing `bemoji` and will
remain in the shell environment.
Or they can be set for just a single run of `bemoji` like this:
```sh
BEMOJI_ECHO_NEWLINE=true BEMOJI_PRIVATE_MODE=true bemoji
```
This is especially useful for advanced configurations like custom commands which do not have an
equivalent option to be set. Be careful with setting environment variables as setting them wrong
or forgetting about them can have detrimental impacts on the functionality of this program!
