v1.6.6

• Added clink history --no-show-time to allow omitting history timestamps even when the history.time_stamp setting is show.
• Fixed match display to not right justify descriptions when the screen isn't wide enough or when descriptions contain aligned columns (like clink set completions do since v1.6.3).
• Fixed clink history when output is redirected; strip any escape codes that might be embedded in the time format.
• Fixed #569; cmd /e:off causes syntax error in clink.bat script.
• Fixed #567; clink history compact accidentally deletes all timestamps.
• Fixed documentation error in Lua API Reference about "w" mode in io.open() and io.sopen() (the behavior was correct, but the documentation was inaccurate/unclear).
