This is for use by the cbl-log and cblite tools.

  • New class TextLogDecoder parses LiteCore text logs the same way as LogDecode does for binary logs.
  • MultiLogDecoder recognizes when a log file is text, and opens it using a TextLogDecoder.
  • Fixed a few minor bugs in MultiLogDecoder.
  • Added a few more ANSI escape codes to Tool.hh

Flag parser now supports --flag=value
d10d263 
During parsing the `=value` part is removed from the flag name,
and a call to `nextArg()` in a handler will return that value.
