This will allow pages to skip loading data from backends like the
database or the wallet RPC server. If a cached page is detected and
valid, all dynamic content generation will be skipped completely.
Other pages that have not been adjusted in this commit will still fetch
backend data all the time. This will ensure clients always see the most
recent data, like worker information or account changes.
This should fix#309 completely but needs some testing.
This will remove any template content related to the trade currency if
that one is left empty in the configuration.
While going through the templates I also cleaned up the PHP Warnings
left. The code and templates should now process without throwing any PHP
warnings.
Fixes#305 and further addresses #301
* Currently no GUI, use DB access to change the row entry
* Upgraded Database table `accounts` with upgrade SQL
* Updated `admin` field to `is_admin` as boolean
* Modified pages, classes, templates to support is_admin and is_locked
