First opam release candidate

[sagotch]

Changes summary:

• More tests.
• The way values are stored changed: instead of indexing values with full path (tab1.tab2.(...).key.value), a tomlTable is a table of tomlEntries (indexed by their key): a direct value (TValue) or a subtable (TTable). It makes the structure a little bit more complex but it is really simpler to handle, especially when you want to retreive a list of subtables you do not know the name to iterate on it.
• Added some getters to help retreiving values from a table.
• Added method to read from a channel or a lexbuf.

OK, I read it all, it's shitload of excellent work. Congrats ! :confetti_ball:

I've made some remarks, but they are easy. My only two point of frustration are the TEntrie type and the getters, I'll suggest something soon.

[sagotch]

You are right about the tomlEntrie thing (I was not really convinced about it, to be honest). Moving TTable to tomlValue should be trivial, I'll push a fix later this afternoon.
