9a5dbbc255 Fix the order of processing #012/LF 
Remove unnecessary columns first and unwind #012 (octal replacement of
LF) second. Otherwise, important content would be lost.

41a51a7e2a Rework removal of unused information 
The columns left to the oom are not used. With this change, the
algorithm becomes more robust and can better handle known special
cases like "kernel:<processname>".

1abf455711 Use Webdriver Manager for browser compatibility 
Version mismatch between browser and selenium driver breaks the tests.
The Webdriver manager automatically ensures the compatibility by
downloading the right driver for the installed browser.

easier to change the name in a test case.

1292d4f1e2 Pin build process to Python 3.7 
After a package update, transcrypt produces incomplete JS:
__target__/OOMAnalyser.js (147:15)
145:       }
146:       if (cols_to_strip) {
147:         var line = ;
                        ^
148:       }
149:       if (line.startswith ('kernel:')) {

instead of
 146       if (cols_to_strip) {
 147         var line = __getitem__ ((function () {
 148           var __accu0__ = line;
 149           return __call__ (__accu0__.py_split, __accu0__, '     ', cols_to_strip);
 150         }) (), __neg__ (1));
 151       }
 152       if (line.startswith ('kernel:')) {

A temporary pinning of Transcrypt to Python 3.7 solves this issue.

d964d657ba Allow all non-whitespace chars in program names 
Program names in Posix can contain all characters expect the null byte.
The code allows \S (all non-whitespaces) and spaces in program names.
This excluded some allowed characters like \n, \r and \t. No negative
effects should arise from this.

967d231be5 Use transcrypt --sform to enable string formatting 
The Python string formatting mini language isn't enabled by default.
"{}".format(42) works fine but "{0:x}.format(42)" returns "{0:x}"
instead of "2a" if the mini language isn't enabled.

674ea295a8 Line "Killed process" can contain the process UID 
Newer Red Hat 7 releases changes the output of the OOM a little bit. The
last output line "Killed process" contains the process UID now.

    anon-rss:20629004kB, file-rss:0kB, shmem-rss:0kB
