Enhanced Date Filtering

Originally using the date feature caused it to a lot of date based comparisons. However since it is expected that a log should cover one day this was too much.

Please note logs DO NOT COVER ONE DAY. They in fact span as long as they have to so long as your don't turn off the client. This may have changed... However this enhancement should allow a user to quickly search a week or a month even a year without having to search every file to see if just one line from that log was within the time frame.
