Bug 1308587 Part 2 - Remove -moz prefix for all multi-column properties in testing and css files. r=dholbert
This patch is generated by the following script:
```
function remove_column_prefix() {
echo "Renaming $1 to $2"
find .\
-type f\
! -path "./obj*"\
! -path "./.git"\
! -path "./.hg"\
\( -name "*.html" -or\
-name "*.xhtml" -or\
-name "*.xht" -or\
-name "*.xul" -or\
-name "*.xml" -or\
-name "*.css" \)\
-exec sed -i -e "s/$1/$2/g" "{}" \;
}
remove_column_prefix "-moz-columns" "columns"
remove_column_prefix "-moz-column-width" "column-width"
remove_column_prefix "-moz-column-count" "column-count"
remove_column_prefix "-moz-column-fill" "column-fill"
remove_column_prefix "-moz-column-gap" "column-gap"
remove_column_prefix "-moz-column-rule" "column-rule"
remove_column_prefix "-moz-column-rule-width" "column-rule-width"
remove_column_prefix "-moz-column-rule-color" "column-rule-color"
remove_column_prefix "-moz-column-rule-style" "column-rule-style"
```
Note: after running the above script, I reverted one minor change to the
file multicol-nested-column-rule-001.xht in the theoretically read-only
directory layout/reftests/w3c-css/received/css-multicol/.
