lcdconf2model: Ensure that DriverPath will end with a slash
lcdconf2model: default value mentioned with parameters are used as upstream_default
lcdconf2model: don't initialise Hello and GoodBye arrays
lcdconf2model: ignore default value from example when square brackets are specified

I.e. in the following case:
# Sets the reporting level; [ default: 2 ] (warnings and errors only).
#ReportLevel=3

ReportLevel default value will be '3'.
lcdconf2model: yes,no values are now boolean (requires Config::Model 2.043)
LCDd.conf: fix ReportLevel default value
LCDd.conf: Make sure that Foreground becomes a boolean
fixed test to remove GoodBye message
