New build in variables: #PROGRAMPATH#, #SETTINGSPATH#, #SKINSPATH#, #PLUGINSPATH#, #ADDONSPATH# and #CURRENTPATH# (this is the path where the ini file that is currently read is located).

If there is a file called Default.ini in the program folder it will be used as the default settings file for new users.
The location of the settings file (rainmeter.ini) can be defined as a command line argument.
