Loopy Lama

New features:

• Enable line groupers on the agent. Each log file may specify line grouping rules in its configuration. The agent can use this to group consecutive log lines together into a single logic log line. All future sampling and redaction rules will work on this single line instead of the individual log lines.

Bug fixes:

• Close file handles for files being scanned that have not had any activity in the last hour. Should fix too many open files bug.
• Reduce the default max_line_size value to 3400 to avoid truncation issues introduced by the server.
