ScanErrLog

Copyright strings have been updated.

The obsolete jahtml module is no longer needed. This release now requires the
jaxml module, version 2.22 or higher, and it works fine with ReportLab 1.06.

A missing import statement caused the previous release of the program to crash immediately (at least under Solaris). This version fixes this problem.

When using the --continue option, an illegal seek error was possible, and crashed the program under certain circumstances. This release fixes that bug.

A new option (-c | --continue) was added to cache statistics in a file between many runs of ScanErrLog on the same, possibly ever growing, file. This change dramatically improves the parsing performance if you parse the same file many times (e.g. every day or week). This is not fully tested but seems to work well. Input file reading optimisations were also done, which greatly improve performance on big files.
