This will fix an issue with templates of other users being applied to
different users logged in. Basically the first cached page would be
displayed for all users.
Created a new cache key for smarty to allow the user ID to be reference
in the cache key. Hence each user has their own cached file which will
be used.
Improved caching by creating subdirectories for cached files. This way
we won't run into a file limit per directory with a lot of cached files.
This fixes#430 and the mentioned issue in that report.
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.
