bug: parser unrecoverably fails if there is a `#+TODO: (...)` directive about orgajs

[xiaoxinghu]

it is caused by the () in the TODO directive. Normally we don't expect to see non-alphanumeric characters in todo keywords, but it's a risk to break the whole parser. It's fixed in v0.5.3, please verify. Thanks for the good finding.

Thanks for the quick update. I can verify that this issue is fixed on windows (node v9.5.0) and on linux (v10.6.0). On linux (v8.0.0, v8.9.3) the parser fails with

./orgajs/node_modules/orga/lib/inline.js:63
        throw _iteratorError;
        ^

SyntaxError: Invalid regular expression: /(.*?(?:[\s\({'"]|^))\*([^,'"\s].*?)(?<=[^,'"\s])\*((?:[\s-\.,:!?'\)}]|$).*)/: Invalid group

for orga >= 0.5.2; though, this is likely a separate issue

@whacked will try that out when I got chance. Thanks a lot.
