Support spaces in tags for import parser

[Fivefold]

Is your feature request related to a problem? Please describe.
LinkAce supports spaces in tags (e.g. "my tag") and uses commas as separator. The importer considers both commas and spaces as separator, so if you had a link in your exported bookmarks like this:

<DT><A HREF="http://testlink.test/" ADD_DATE="1468778724" TAGS="test tag1,test_tag2">Testlink</A>

it would import with the tags test, tag1 and test_tag2

Describe the solution you'd like
Support spaces in tags, since LinkAce itself supports them.

Describe alternatives you've considered
Putting the spaces in Apostrophes in the imported .html file (i.e. TAGS="'test tag1','test_tag2'"> gets imported as 'test', 'tag1' and 'test_tag2'

Additional context
This seems to be related to the used shaarli bookmark parser (see sebsauvage/Shaarli#22).

Hi! thanks for taking the time to write the feature request. I am closing this in favor of #316 where this was already mentioned. Please consider following this issue instead.

Just for further clarification: I tried out @krylm's snippet from #316 and it seems it aggregates all tags into one (i.e. in my example above you would get one tag test tag1,test_tag2). This is not the behaviour I'm asking for, I don't know how Google Bookmark Manager handles tags though.

Because I'm not too familiar with php and can't debug without setting up a dev environment with LinkAce I will work around by changing all spaces in tags to underscores before import and then changing them back manually in Linkace. I don't have many tags with spaces in them fortunately.

Yes, I understand. Will keep this in mind.
