code: public int getInt(String category, String key) {
  		String value = this.getProperty(category, key).toLowerCase().trim();
  		return Integer.parseInt(value);
  	}
docs: Same as {@link Configuration#getProperty(String, String)}, but a integer is parsed.
  
  @param category The category of the property
  @param key      The key (identifier) of the property
  @return the integer value parsed from the property
