log4c-1.3.1

In this release there are now appenders for stderr and stdout.
Previously you would have to use this syntax to output on stderr:

    <category name="root" priority="trace" appender="stderr" />
    <appender name="stderr" type="stream" layout="dated"/>

Where the "stream" type would use the appenders name to open for
output. Now you can use this syntax:

    <category name="root" priority="trace" appender="testing" />
    <appender name="testing" type="stderr" layout="dated"/>

Which makes the configuration file more compatiable with other
implementations.

log4c-1.3.0

In this release there is a new static file appender. This appender opens
the file, writes the log message and then closes the file. This allows
other processes to monitor the log file. You can now add a cutom parser for
an appender. This allows you to extend the syntax used for an appender.

Summary of the changes:

• added a static file appender.
• added the ability to load a custom parser for an appender.
• removed the basic_r, dated_r and dated_local_r appenders.
