Adds report highlighting and move line up/down features, bug fix

Feature additions:

• PPCL reports are now properly highlighted.

  • Untraced lines are grayed out.
  • Unresolved lines are highlighted in red.

• Added support for moving a line(s) of code up/down without moving the line number.

  • With the cursor on the line you want to move (or with multiple lines selected) pressing ctrl + shift + ↑ or ↓

Bugfixes:

• Help popup error
• Fixed an issue when the enter key was pressed at the beginning of a line of code, a new line was inserted below, but the code and cursor stayed on the current line, and subsequent presses triggered an auto-increment warning.
