v0.7.0

This marks the restart of development on otime

This is the first release of the new development run on otime, this is built in a new way where at some point otime will be a completely separate library instead and the executable will just be a wrapper around it for use on cmd-line and such.

This removes the -csv feature from the executable but adds -convert instead, this will convert ctime files (so also files from v0.6 and down) to the new otm1 file format that it will use going forward, otm2 is probably not too far off when start allowing for some of the features I would like to do too, but I will also write a converter then.
