Fscrawler save binary , base64

[Yimjunhyeok (임준혁)]

For example, word or excel files.

conf ==>
"store_source" : true
"index_content" : true
"indexed_chars" : "-1"

==> Successfully save the binary attachment.

"store_source" : true
"index_content" : false
"indexed_chars" : "-1"

==> Not save the binary attachment.

Actually i want to save the binary attachment without text extraction.
