Summary0003801: new/delete used instead of std::unique_ptr/std::make_unique
DescriptionI tried to write a coherent description here, but I couldn't?

std::unique_ptr seems to be a better practice, instead of new/delete. Since C++11. Doomseeker (and Wadseeker) uses C++98 style new/delete.
And std::make_unique seems even better. Since C++14.

Let's modernize?
Steps To Reproduce
$ grep -r 'new ' src/ | wc -l
586
$ grep -r 'new\[\]' src/ | wc -l
0
$ grep -r 'delete\[\]' src/ | wc -l
8
$ grep -r 'delete ' src/ | wc -l
180
$ grep -r 'unique_ptr' src/ | wc -l
0

While this is a good idea, libraries shouldn't be touched. Also, while smart pointers will work, you could look for alternatives in each case. For instance:

diff --git a/src/wadseeker/zip/unarchive.cpp b/src/wadseeker/zip/unarchive.cpp
index 55f0a04a..9aeff22a 100644
--- a/src/wadseeker/zip/unarchive.cpp
+++ b/src/wadseeker/zip/unarchive.cpp

Should we use std::unique_ptr or Qt's QScopedPointer?
Mumble decided to go with STL pointers.https://github.com/mumble-voip/mumble/issues/3937 [^]

Since we are already using QScopedPointer, we should stick to that :)
