Fixed timeline creation, API logical fixes.

* Resolved issues:

    * #0006: Fix timeline menu UI.
    * #0015: Create new timeline button in timeline menu.
    * #0017: Implement timeline creation.

* Removed ts_api:post_timeline/3, corresponded to `POST` to
  `/ts_api/timelines/<user-id>`, which makes no sense as there is no way to
  auto-generate new timeline-ids.
* Changed ts_api:put_timeline/3 to use ts_timeline:write. This resolved #0017.
* Changed ts_api:put_entry/4 to use ts_entry:write.
* Implemented ts_entry:write/1 and ts_timeline:write/1. These functions are
  simple passthroughs to mnesia:dirty_write/1.
* Added clarifing documentation for ts_json:record_to_ejson JSON formats.
* Renamed ts_json:ejson_to_record/2 to ts_json:ejson_to_record_strict/2 and
  added ts_json:ejson_to_record/2 as a lax version of the same.
* Updated all ts_api functions to use updated ts_json methods.
