Software versioning and upgrades

LwCad plugin is using standard versioning using major and minor numbers.
Higher number means a newer version.
Example : LwCad 5.2 - major version is 5 and minor version is 2.

1. major upgrades
    Major upgrades are always paid. License with lower version can by upgraded to latest license for special upgrade price. Upgrade price depends on the difference between an old license number and the latest license number.
The older versions have the bigger upgrade price.
If your license is older than a minimum upgrade version then you have to purchase a new full license.

2. minor upgrades
    Minor upgrades are always free. Licenses with the same major number can be upgraded to latest version with no restrictions.
