Properly handle hanging deparser

[cynovg]

After every start IDE i see warning about outadet XSubs declarations. When you try to regenerate, the process starts in the background and does not end. It is repeated in all projects, an attempt to roll back the IDE version did not lead to anything. This leads to the fact that some of the functions do not work. For example, renaming a function (Shift+F6).

After stopping the IDE, I see a sleeping process:

 48725 ?        S      0:00 /usr/bin/perl -I/home/cynovg/audiofile-info/lib /home/cynovg/.local/share/JetBrains/Toolbox/apps/CLion/ch-0/221.5080.224.plugins/plugin/perl/xs_parser_simple.pl

When I try to run the process from the terminal, I see:

/usr/bin/perl -I/home/cynovg/audiofile-info/lib /home/cynovg/.local/share/JetBrains/Toolbox/apps/CLion/ch-0/221.5080.224.plugins/plugin/perl/xs_parser_simple.pl

Basically you should do:

1. Uncomment https://github.com/Camelcade/Perl5-IDEA/blob/master/plugin/scripts/xs_parser_simple.pl#L14
2. Run script from the console
3. See on which module script stucks
4. Try perl -MScript::In::Question it should do nothing (not hang not crush)
5. If it does - worth asking module author - why.

We could add the heartbeat message to the deparsing script and catch if it not finished and silent for a long time. And kill it by ourselves.

We could probably even show in progress - what are we currently doing. Indicator may be used with possibility to cancel.
