For 0.2.0 I'm looking at adding:

• Key/value delete
• Key/value append insert
• Key modification
• Table and Array of Table add insert
• Table and Array of Table delete
• Table and Array of Table modify
• More error reporting
• Remove dependence on regexes to allow tomllib to build on stable
• First tomlkit release

Since I'm moving soon and the prep and actual move will be taking so much time, I'm going to limit 0.2.0 features to just what's needed to get cargo-edit up and running. However I'm adding a change to let tomllib to compile on stable. There's only 4 regexes I need to eliminate for that to happen.

2016-06-14: Adding tomlkit release since there's interest in it and it shouldn't be too bad (there's not a lot of functionality to implement).
