Subject: [PATCH] Gratis premium account (#156)

* skip premdays and lastdays calculation when premdays = 65535 (gratis premium in TFS)

* TFS consider 65535 as gratis premium account and PHP_INT_MAX does not assume this value

* adds condition of premdays=65535 and standardize the label "gratis premium account" with tibia client

* adjust the label "days" when there is only one day of premium account

* adjusted premium account status

* Some small adjustment

* Sorry, typo.
