Bash functions for Healing

This function library contains bash shell functions related to improve the Health of a player.
Though it had been tested with the busybox ash shell, some functions might only work correctly in bash ( or the other way around ).

The functions use code from

1. cf_funcs_common_sh
2. cf_funcs_requests_sh
3. cf_funcs_items_sh

These client side scripting files are suggested to be installed inside the user's “HOME/.crossfire/s/” folder,
with a shortcut link cf → to the .crossfire directory,
to do have not much typing to do in the client's commandline.

Functions are usually named _function(){ ;} , functions named _ _function and _ _ _function are usually alternatives to the _function.

The main function currently is _check_hp, which calls _ _check_hp, which is not an alternative function for _check_hp here in the code.

The function _heal applies a parameter to increase hit points, falls back to the HEAL_ITEM variable.
The HEAL_ITEM variable can be set to something like HEAL_ITEM=“rod of heal” in calling scripts.
