fix blockcode render, more test cases passed
detail fix. 44/48 tests passed, just as the master branch
export Renderer
convenience parse api

this is not a bugfix, version bump to 0.3. remove preferGlobal, coz it is a lib more than a program
remove the convient way
global leak of flags
make example more clearly
configure Travis CI services
skip tests that are known to fail, as enumerated in chjj/marked#136
