fix: two annoying bugs when operating on *slime-apropos* and *slime-inspector* buffers
fix: corretcly recover point in trace dialog buffer

also more readable cl-style `slime-trace-dialog-refresh' macro
add: report status and traced specs separately

status is just the available traces for now...
add: flash overlays when updating
fix: escape some characters when reporting traces using SWANK::TO-LINE
fix: better, storage, reporting and control of traced specs

Still needs some work and still buggy since a complex spec traced
only normally (an "orphan" spec) cant be retraced for the dialog.
fix: formatting fix
fix: needs to be CL:PROGN
