This commit makes it possible to filter only crashes caught by ABRT.

Firstly the button group for selecting priority was replaced by
dropdown list. This also meant rewriting the piece of code that set
'active' class to change text of selected priority level.

Secondly, when option `Only Problems` was selected another condition is
added to match only items that have syslog identifier equal to
`abrt-notification`.

In the log overview display different icon for problems (logs with
        priority lower that 4 have a triangle with exclamation mark,
        ABRT's problems after this commit have cross mark).

Since log entry from ABRT can contain quite some data and some of them
are rather long strings, three thing were done in this commit:
1. Split data to three categories - General, Problem Info and Problem
Details
2. Remove all "PROBLEM_" prefixes to make it more readable
3. Long items (in Problem details) show as accordion

FAF is platform for collecting and analysis of crashes. This is first
step for reporting problems from Cockpit. Second step will be reporting
to Bugzilla.

When problem is reported, display clickable 'Reported' text which sends you
to FAF.
When problem is reportable, display button for reporting.
