--- Parses a map of key-value pairs into a table.
-- For example, "count 25000 speed 0.8 rate_erosion 0.006 doawesome true" would be parsed into
-- the following table: { count = 25000, speed = 0.8, rate_erosion = 0.006, doawesome = true }.
-- @param	params_text	string	The string to parse.
-- @returns	table		A table of key-value pairs parsed out from the given string.
