This should fix an edge case where AT states data was pruned/trimmed but it was then later required in consensus. The older state was deleted because it was replaced by a new "latest" state in a brand new block. But once the new "latest" state was orphaned from the block, the old "latest" state was then required again.
This works around the problem by excluding very recent blocks in the latest AT states data, so that it is unaffected by real-time sync activity.
The trade off is that we could end up retaining more AT states than needed, so a secondary cleanup process may need to run at some time in the future to remove these. But it should only be a minimal amount of data, and can be cleaned up with a single query. This would have been happening to a certain degree already.

Examples:
### Get URL to load a QDN resource
```
let url = await qortalRequest({
action: "GET_QDN_RESOURCE_URL",
service: "THUMBNAIL",
name: "QortalDemo",
identifier: "qortal_avatar"
// path: "filename.jpg" // optional - not needed if resource contains only one file
});
```
### Get URL to load a QDN website
```
let url = await qortalRequest({
action: "GET_QDN_RESOURCE_URL",
service: "WEBSITE",
name: "QortalDemo",
});
```
### Get URL to load a specific file from a QDN website
```
let url = await qortalRequest({
action: "GET_QDN_RESOURCE_URL",
service: "WEBSITE",
name: "AlphaX",
path: "/assets/img/logo.png"
});
```
The URL used to access the gateway is now interpreted, and the most appropriate resource is served. This means it can be used in different ways to retrieve any type of content from QDN. For example:
/QortalDemo
/QortalDemo/minting-leveling/index.html
/WEBSITE/QortalDemo
/WEBSITE/QortalDemo/minting-leveling/index.html
/APP/QortalDemo
/THUMBNAIL/QortalDemo/qortal_avatar
/QCHAT_IMAGE/birtydasterd/qchat_BfBeCz
/ARBITRARY_DATA/PirateChainWallet/LiteWalletJNI/coinparams.json
This allows any QDN resource (e.g. an IMAGE) to be linked to from a website/app and then rendered on screen. It isn't yet supported in gateway or domain map mode, as these need some more thought.
The simplest way to link to another QDN website is to include a link with the format:
<a href="qortal://WEBSITE/QortalDemo">link text</a>
This can be expanded to link to a specific path, e.g:
<a href="qortal://WEBSITE/QortalDemo/minting-leveling/index.html">link text</a>
Or it can be initiated programatically, via qortalRequest():
let res = await qortalRequest({
action: "LINK_TO_QDN_RESOURCE",
service: "WEBSITE",
name: "QortalDemo",
path: "/minting-leveling/index.html" // Optional
});
Note that qortal:// links don't yet support identifiers, so the above format is not confirmed.
This prevents foreign coins from leaving the local wallet when there is a high probability that the trade will fail, and therefore should reduce the chances of losing transaction fees due to refunds.
Whenever this occurs, the UI will show "Trade has an existing buy request or is pending cancellation." after clicking Buy.
