loolwsd: save documents when timestamp is within 10 seconds
Due to filesystem timestamp precision and other factors
we assume a timestamp match within 10 seconds to mean
the document has been recently saved and store it.
A document has to have an older than 10 seconds
modified timestamp compared to our last timestamp
to be deemed unchanged in the interim and skipped
from storing again.
