Added followSymlink for find-command

[junjihashimoto]

Hi,

Currently, find-command can not follow symlink like 'find -L'.
See this code.
This PR adds followSymlink-flag to follow symlinks.

Sorry for not reading #21.
(Now I read it.)

If there is a DSL and its implementation for find-command, it will be better than this PR.

I suppose the DSL will change filter-options and search-area of file system.

In use case of changing filter-options, we can use findWhen, so we do not need additional function for shelly.

In use case of changing search-area, we can refer to linux-find-command.
In this manual, the option of search-area is just whether to follow symlinks or not.

I think we need just a option of following symlinks and do not need DSL.
(To solve my job, I need this option. If you have any alternative solution, please tell me.)

Any suggestions are welcome.
Should I implement DSL version of symlink?

Thanks for the PR. I agree that something find-specific would be better, but this seems fine. Would you like me to merge it now?

[junjihashimoto]

I'd love to！
It would be a great help.
I am using my branch.
