Attempt to generate segment names for cc65 This worked, sort of. The problem is that SourceGen will revert to hex output in certain situations, such as a broken symbolic reference. There happens to be one in the ZIPPY example, and it's on a relative branch. The goal with the segment stuff is to allow cc65 to treat the source as relocatable code. In that context, a relative branch to an absolute address doesn't make any sense, so the assembler reports a range error. We don't currently have a mechanism that guarantees no references are broken (and no affordance for finding them), so we can't make this mode the default yet. Instead, we continue to use the generic config, but generate the correct set of lines as comments. (issue #39)

Add custom flag updaters for ROL/ROR There are some useful interactions between C/N and maybe Z. Added a quick test to 1003-flags-and-branches. Also, updated the 2008-address-changes tests. Change b37d3dba extended the nearby-target range of out-of-file symbols by one, so one line that didn't get an operand label now does.

Fix code tracing bug If you set things up just right, it's possible for flag status changes to fail to get merged. Added a regression test to 1003-flags-and-branches. Also, tweaked the instruction operand editor to be a bit smoother from the keyboard: added alt-key shortcuts, and put the focus on the OK button after creating/editing a label so you can just hit the return key twice.
