0.8.1

Updated xcodeproj and all .plist files to show version 0.7.3 and fixed a bug that could cause a tunnel that terminated too quickly to be deallocated while the termination notification was still being processed. The changes include a number of "whitespace" changes as a side effect of adding and then removing a large number of conditional NSLog() messages to diagnose the bug.

Build a universal binary in the Deployment configuration, target 10.3 on

Clean up formatting and minor logic changes in SSHTunnel.

Refactor the guts of SSHAgent - handleAgentConnections and inputFromClient:. Big changes are giving variables more sensible names, moving declarations to first use, and simplifying logic to reduce levels of nested conditionals. This is a very invasive change, but I'm confident that behaviour is the same.

Code cleanup: remove unused code, actually allocate the locks in initWithPaths, add accessors for addingKeys, and simplify logic to reduce nested if/else statements.
