Summarize the issues that discussed these changes

This is my first pr in this project and I didn't know the rule "Opened an issue discussing these changes before opening the PR". Since I've already did all the work I hope it is ok if I open it anyway. Sorry for the inconvenience.

Changes

Added ignoreTrailingSlash router option.

What does this PR do?

find-my-way does not support by default trailing slash in routes, so /path and /path/ are not the same thing (and the one with the trailing slash will be a 404).

If a user needs this specific behaviour it can pass { ignoreTrailingSlash: true } to find-my-way. The result will be that internally find-my-way will register two routes /path and /path/, this will be seen in the debug log.

This pr add the possibility to pass this option (and possibly more) to find-my-way.

@hekike can you review? Thanks.
