Milestone Release v1_beta8 - 10/20/15

File reader API can now convert the contents of a file to a blob.

sol-message-digest API got in. With that, Soletta now handles common
message digest algorithms like CRC32, MD5, SHA1, SHA256 and SHA512.
There are two possible backends (linux-kcapi -- defalt one -- and
openssl).

sol-fbp-generator got more fixes and should be more robust.

The grove/lcd* nodes had their issues fixed. A new form/selector node
was created, to be used together with the grove/lcd-string one. It
formats a given list of items nicely for those displays and handles
selections in that list.

The composed types API got simpler and more similar to the pristine
packet types API.

Finally, smalls fixes detected by different scenarios on our checks,
were made: we now pass on i386 systems and under timezones with DST on.
