created a build script for the applet.  the script will create an archive
which includes the felix library and the felix properties file. It will
optionally deploy the jar to a specified web folder.
ignoring release and target in gitignore
more documentation about the build
* the felix properties file was referencing an old jar that no longer exists
  in the build process

* added a note into the build script to remind the end user to re-run
* the jitsi build in order to re-generate the bundles if the property
* onsip.cache.version was modified. in practice, this reminder is not
* necessary because if this property was modified, then we've already
* built the bundles. however, in some edge cases if we've updated
* this property, but not the bundles, java would not download a fresh
* copy of the our bundle set. java would instead reuse the bundles
* out of cache.
streamlined some of the jar url references
minor change in documentation instructions
reset default property value
added capabilities functionality to verify that our environment is
capable of running the jitsi phone
removed a duplicate function which was doing os detection.
* support for mac os x 10.5

* added input device detection to capabilities object
appletlauncher: opted to remove a piece of code that may or may not assist
in rebounding the application.  the idea was if the framework failed to
launch then perhaps one of the bundles was corrupted, so as a precaution
we would remove the entire cache. this condition simply hasn't proved
to have occurred in recent history so we probably don't need to account for it.
enhanced feature set to include transfers and conferecing.
hold: typo
* enhanced the register api call to support proxy server configuration
  at runtime

* enhanced the applet by supporting proxy server configuration
  through the parameter set passed into the embed / object tag
an extensive update in support of multiple registrations in the jitsi applet.
added many enhancements in streamlining error handling
updater: modified the updater logic to account for old version of the app that
         did not generate a version number. the new logic stipulates that if
         the version details don't exist then assume an old version of the app.
build: enhanced script to include jar signing
build: added a conditional flag that signs the jar. we may not always
  want to sign the jar if we're developing for instance.
build: annotation on jar signing
