Added tag c_timesys_0.3.0 for changeset 851fe84b6d97
Removed tag 0.3.0
Add next_uint8 and next_uint16 functions for each generator.
next_uint8 replaces next_byte of the previous version
(which was implemented for KISS only).
Add test of simplerandom_cong_next_uint8() and simplerandom_cong_next_uint16() to test_simple.c.
Add test_simple.c to 'make check' command.
Merge branch 'master' into timesys
