If the `manual` parameter is assigned a date in the form of
`YYMMDD`, this will tell uBO to update lists from origin sources
when the current time is within the range of the specified date,
otherwise lists will be updated from CDNs. Updating from CDNs
is always strongly recommended since this enables differential
updates.
For the time being, `manual=1` will always cause to update lists
from origin, but this form will be deprecated once next stable
release is widespread. The idea is to not leave behind stale
and obsolete links which would be detrimental to differential
updates should someone click on one of these old links left
behind.
Purging all the lists from cache storage is detrimental to
differential update, and cause filter lists to be updated less
often and consequently to be less up to date then when letting
differential updater do its work.

Also reported internally, steps to reproduce the issue fixed here:
- Open uBO's dashboard through 3-dot > Add-ons > uBO > Settings
- Bring forth "Filter lists" pane
We want the tab to be already opened at next launch
- Quit Firefox for Android
- Launch Firefox for Android
Result:
Very long launch time, lists marked as out of date.
In Support pane's troubleshooting information, a delta sign will
be added to list update information when the list was last updated
through differential update.

To work around incompatibity with `urltransform` in 1.53.0.
With this commit support for `urltransform` is dropped in
favor of `uritransform`. Since `uritransform` won't be parsed
by older versions of uBO, the change in syntax for `urltransform`
between 1.53.0 and 1.54.0 will no longer cause issue.
