Initial revisions to API v8

* Added .gitignore file to ignore vi swap files
* Moved readme to Markdown extension for better display on GitHub
* Revised script to use v8 of the API and the changes to how the API calls query and return data. Primarily this meant no {{url}}.json and removing the data elemenet from the returned data
Fixes #1 - remove time entry testing

* updated the print_time_entries to always display the task id and the help documention
* also _temporarily_ removed the date limits on list_time_entries to speed the transition to v8
Updating documentation
Fixes #2 - starting time entry with project

The old API took the project as a sub-element in the JSON, v8 accepts the project id as a pid index in the JSON.
Displays project name when showing a time entry

API v8 returns the project id, so a new function was written to find the project by id.
Fixes #7 #5 - fixed date limits to the v8 format

* updated get_time_entries date limits to use the timezone from the .togglrc file as well as comply to the new v8 date format (ISO8601)
* updated the documentation
Fixes #3 - look up default workspace id

* To list the projects, the v8 API requires the workspace id.
* added new function get_user to retrieve the user object which contains the default workspace.
* updated the get_projects to use this new API call.
Updated readme documentation
Updated link to issues
Fixes #5 - bad date sorting on ls function

* Sort the time entry dats by the timezone configured in .togglrc

NB: Most of the dates submitted to the API are converted to UTC. While this is not necessary with v8 that was the way the original code was written. It works, but it might be confusing. It woulnd't hurt to clean that up, but its not necessary.
