ps_version_compliancy

[gaillafr]

Due to a bug with the core of PrestaShop, using ps_version_compliancy that include PS 1.5* in its range will cause crashes.
The line should be removed.

Also you define MIN_VERSION and MAX_VERSION but they were not used for the ps_version_compliancy.

To follow PrestaShop core updates, I suggest you use the PS_VERSION constant to check the max version instead of trying to use '1.7' (hardcoded).
