Add support for MS HTTP Error logs

[sydp]

Log files were found in a subfolder under %SystemRoot%\System32\LogFiles

Example file header:

#Software: Microsoft HTTP API 2.0
#Version: 1.0
#Date: YYYY-MM-DD HH:MM:SS
#Fields: date time c-ip c-port s-ip s-port cs-version cs-method cs-uri streamid streamid_ex sc-status s-siteid s-reason s-queuename transport

Some of the fields look like they are documented on this page:
