* Split a command based on what's between brackets, strings not in brackets are ignored
* \param command: the command to split.
The command will be split to all fields between '[]'. If you want a '[' or ']' in your command, precede it by a '\'
If you want a '\', precede it by another '\': '\\' => '\'
All other escape chars are resolved to the char itself: '\c' => 'c'
* \param result: if this value is not NULL, this array will be filled with pointers to the different parts.
* The pointers point to memory in the original command.
* Make sure it's big enough
* \param logContext: if not NULL this will be used to log syntax errors.
* \return: negative if there is a syntax error, otherwise the number of parts
* NOTE: command will be modified if result != NULL, \0 will be inserted and escape chars are removed if followed by [ or ]
* NOTE: syntax error message can be very cryptic if result != NULL => check with result == NULL for syntax errors first
* example:
cmd = "lol [command] ignored [arg1] [arg2]"
will result in the following result:
- result[0] = "command"
- result[1] = "arg1"
- result[2] = "arg2"
with as return value 3
