Add Archive_Tar class to lib/
Some AUR setups do not have PEAR available. While other setups have access to outdated Archive_Tar versions. Avoid these problems completely by including the necessary files for Archive_Tar in lib/. Remove Archive_Tar requirement from INSTALL doc. Signed-off-by: canyonknight <canyonknight@gmail.com>

+ * Base class for other PEAR classes. Provides rudimentary

+ *
+ * If you want a destructor in your class, inherit PEAR and make a
+ * destructor method called _yourclassname (same name as the
+ * constructor, but with a "_" prefix). Also, in your constructor you
+ * have to call the PEAR constructor: $this->PEAR();.
+ * The destructor method will be called without parameters. Note that
+ * at in some SAPI implementations (such as Apache), any output during
+ * the request shutdown (in which destructors are called) seems to be
+ * discarded. If you need to get any debug information from your
+ * destructor, use error_log(), syslog() or something similar.
+ *
+ * IMPORTANT! To use the emulated destructors you need to create the
+ * objects by reference: $obj =& new PEAR_child;
