Minimum value per level and enhanced damage item stats fix (#26)

* Added a temporary fix to have a minimum value of 1 for per level mods

* Expose Stat Aliases and Type Aliases (#25)

* Fixed setting a minimum value of 1 for per level item stats

* Added minimum value of attack rating per level to be 15

* Added min value for replenish durability/quantity

* Added fix for reading item modifiers - enhanced damage now works

* Delete .idea/.gitignore

* Delete .idea/d2go.iml

* Delete .idea/modules.xml

* Delete .idea/vcs.xml

* Added gitignore file

* Refactored code
