Remove .bowerrc

If there are no further comments or suggestions for #2386 then I think it would be good to get this in. Remove .bowerrc from base repo but allows it to still be used for people with specialised dev environments by adding to .gitignore

Fixes race conditions in functional test introduced in PR#2395

fixes PR#2395
- in editor_test.js line 272, I wait until the post settings menu appears, and THEN also wait until the delete post button appears, rather than just waiting for the first condition, this can result in a race condition which has been seen.
- in editor_test.js line 229, I click on the tag, then wait until it disappears, rather than asserting the tag doesn't exist immediately.  This could potentially result in a race condition, but I have not seen it yet.
- in editr_test.js line 315, I click on the delete post button, and now wait for the modal container to appear before clicking the accept button.  This could result in a race condition, but I have not seen it yet.
