Add short versions of CLI options

Add single or couple letter short options and two letter short commands.
Single letter short options can be passed in a single joined form, for
instance '-dg'.

Also change CLI options constant string literals type to QLatin1String
as we would have to use this as a wrapper anyway wherever the constants
would be used, causing quite long and verbose statements.
