Here, a new timer is added. Before this commit, the parsing was started in CodeCompletion::OnAttach(), after this commit, the parsing is started a bit later (after the application is fully started, and a time period later). Since starting parsing may take several seconds, so delay this task can make C::B start much faster.

Note: When C::B started, it usually do such things

...
scan plugins
for (each plugin)
    run its OnAttach()
...
send event: APP_STARTUP_DONE

But this cause an issue, here is the steps:

1, C::B is started with CodeCompletion plguin disabled.
2, you open a project
3, you enable the Codecompletion plugin
4, *BUG* Codecompletion plugin does not run parsing on already opened project.
