If the package_index.json signature is not valid, a dialog box asking
the user to "update" the index is shown. Previously a java-exception
was printed if running from terminal or the IDE would not start at
all (with no apparent reason) if lanched from GUI.

1. _The_ demonstration code should be complete
2. Search the issues to see if there has been _a_ discussion
3. Each commit should result in _a_ fully functional code
4. one commit per file modified is not _a_ good practice
5. Separate title from _the_ body with a blank line
6. Include _a_ rationale for the change
7. adding unnecessary extra commits to the pull request _,_ you can squash
avoidMultipleOperations becomes false with a 10 seconds timeout after pressing the compile button.
The new code introduced by 99f6043ced didn't take this into account, so the port was being reopened before staring the actual upload.
Also, make uploading variable static to avoid preferences confusion (this should be solved in a saner way giving every Editor instance its own set of properties, but it will hopefully fixes by the cli integration and workspace concept)
- Use LinkedList with ListIterator to make all methods except for `clear()` run in `O(1)` (constant runtime) instead of `O(n)` (linear runtime).
- No longer store executed commands that are executed multiple times (executing {1, 1, 1, 1, 2} now only adds {1, 2} to the history).
The behavior is as follows:
- Pressing the UP key will select older commands.
- Pressing the DOWN key will select newer commands, restoring the last unexecuted command if available.
- Pressing the ESC key will reset the input field to the latest unexecuted command and reset the traversal location. Pressing ESC while the latest unexecuted command is selected will clear the input field.
This fixes#4891, with the difference that the proposed solution has a command history per Arduino session and this implementation has a command history per serial monitor start.
Now ```tar.xz``` format is widely used, and the official arduino
IDE download URL also shows that arduino uses ```tar.xz``` format.
(https://downloads.arduino.cc/arduino-1.8.9-linux64.tar.xz).
As we all know, the tar.xz format has the optimal size compared to tar,
tar.gz, tar.bz2, and zip.
(https://www.rootusers.com/gzip-vs-bzip2-vs-xz-performance-comparison/)
Therefore, it is very unreasonable not to support tar.xz.
Supporting this format can save almost half of the bandwidth resources
and download time when compressing the gcc toolchain,
making users more comfortable.

When creating a new sketch, it is initialized with the BareMinimum example sketch. This example sketch uses 2-width whitespace indentation, which might differ from the user-defined tab settings. This commit makes the generated example sketch consistent with the user-defined tab settings.
- use diamond notation <> to remove redundant type specification
- do no cache listeners, because it makes the code heavier for a
a very small gain in memory usage.
- removed redundant "this" keywords
