Current effects in QED corrections (#767)

* corrected two typos missed during review of PR-719

* changed file permission from executable to read/write

* added current into QED corrections

* corrected tabs

* fixed indent in multifab construction section

* adjusted more indentations that were accidently changed from the origional

* Corrected the curent mesh

* Update Source/FieldSolver/WarpX_QED_Field_Pushers.cpp

Co-Authored-By: Revathi  Jambunathan <41089244+RevathiJambunathan@users.noreply.github.com>

* Correctly implimented Revathi's recommended changes to the E,B and J boxes

* Adjusted comments, tabs, and copyrights

* and EOL
