ESE - Import to Available Items from clipboard

[Pixelated-Grunt]

This change add 2 extra options to the 'Filter' menu strip.

• Import from Clipboard
  • Import ACE arsenal export format array to the 'Available Items' (existing items will be replaced/removed). Available Items list will stay as the imported list until user hit reset
• Reset
  • Reset the 'Available Items' back to all items

This is a simple change by using existing functions to convert clipboard data to have the same data structure as the 'EHN_ENE_itemsHashMap' hashmap. Then replace the 'EHN_ENE_itemsHashMap' variable with the newly created hashmap.

Existing 'EHN_ENE_itemsHashMap' will be saved for the reset function.

It also adds filters to both 'fn_ESE_lbAdd' and 'fn_ESE_lbnAdd' functions to skip items that are blanks (no Display Text). The ESE list boxes contain blank rows, this behavior exist in the current Steam release as well. See before and after screenshots from the Steam release version.
