Use dialog font in editor drop-down

The editor chevron drop-down inherited the SWT system font, which on
many platforms looks out of place compared to the rest of the IDE
chrome. Switch the filter text and the table to JFaceResources
getDialogFont() so the list matches the Quick Switch Editor (Ctrl+E)
dialog and other workbench dialogs.
