/**
* Sets a semi-colon separated list of filters to filter-in or filter-out
* certain types of files when the contents of this directory are requested
* via a GetFilesAndDirectories() call.
*
* Currently supported keywords:
*
* * filter-out-sensitive
* This keyword filters out files or directories that we don't wish to
* make available to Web content because we are concerned that there is
* a risk that users may unwittingly give Web content access to them
* and suffer undesirable consequences. The details of what is
* filtered out can be found in GetDirectoryListingTask::Work.
*
* In future, we will likely support filtering based on filename extensions
* (for example, aFilters could be "*.jpg; *.jpeg; *.gif"), but that isn't
* supported yet. Once supported, files that don't match a specified
* extension (if any are specified) would be filtered out. This
* functionality would allow us to apply the 'accept' attribute from
* <input type=file directory accept="..."> to the results of a directory
* picker operation.
