Clean up my-account template

This patch moves Available Downloads into it's own separate template
file, and moves the titles for Recent Orders and My Addresses into
their respective templates as well. This patch also adds a couple of
new hooks and filters for making templating even easier.

Fix reset password URL to work with non-pretty permalinks
Fix security issue where new password is being changed on non-SSL page.
Hook into WP lostpassword_url filter so that code that calls wp_lostpassword_url() actually uses new lost password page rather
than wp-login.php. For example, WC Login Widget.
Improved the result-count template

- Coding style: mid-line indenting which should be done using spaces.
- Renamed `$max` to `$total`.
- Simplified calculation of `$last`.
- Using en dash between range of values: http://en.wikipedia.org/wiki/Dash#Ranges_of_values.
- Tweaks to the “Showing 1–10 of 12 results” result text:
  - Converted `%s` to `%d`.
  - Used numbered placeholders (like `%1$d` and `%2$d`) which allows for more flexible translations since the placeholders can be swapped and repeated now.
  - Used `_x()` with comment to clarify placeholder order.
- Added two additional texts:
  - One for showing the only single result because “Showing 1–1 of 1 results” is overly verbose.
  - One for when all results are shown on the same page because “Showing 1–8 of 8 results” is a bit too verbose too.
