Optimize our tests to run faster.

Changes include:

 * default tests locale is Polish instead of Spanish

   Rationale: see commit 049f59a.

              tl;dr¹: 1 vs 20 locales to generate, that’s all.

 * flake8 is running on its own build jobs.

   Rationale: we are now able to tell what passed and what didn’t at a
              glance.  We do not have to search through stuff to find out
              what (nosetests or flake8) failed.

 * Use the Travis apt cache, which will save us a few seconds here or
   there.

¹ This commit message is actually longer than the one in 049f59a.

 How to set the locale for Nikola tests?
 ---------------------------------------
 
-For testing nikola needs to specify two languages, each one with a supported locale. By default, the test suite uses ``en`` and ``es`` as languages, and their respective default locale for them.

+The choice of Polish is due to having one locale to generate instead of 20 (Spanish) and you can happily ignore it — just set the language–locale pairs by exporting two shell variables, for example::
 
     export NIKOLA_LOCALE_DEFAULT=en,en_US.utf8
-    export NIKOLA_LOCALE_OTHER=es,es_ES.utf8
+    export NIKOLA_LOCALE_OTHER=pl,pl_PL.utf8
 
 In Windows that would be::
 
-	set NIKOLA_LOCALE_DEFAULT=en,English 
-	set NIKOLA_LOCALE_OTHER=es,Spanish
-	
+    set NIKOLA_LOCALE_DEFAULT=en,English
+    set NIKOLA_LOCALE_OTHER=pl,Polish
+
 Replace the part before the comma with a Nikola translation selector (see ``nikola/conf.py.in`` for details), and the part after the comma with an *installed* glibc locale.
 
 To check if the desired locale is supported in your host you can, in a python console::
 
-	import locale
-	locale.setlocale(locale.LC_ALL, 'locale_name')
-    # by example, 'en_US.utf8' (posix) 'English' (windows)
-	# if it does not traceback, then python can use that locale
+    import locale
+    locale.setlocale(locale.LC_ALL, 'locale_name')
+    # for example, 'en_US.utf8' (posix) 'English' (windows)
+    # if it does not traceback, then python can use that locale
 
 Alternatively, if you have some disk space to spare, you can install
 the two default locales. Here is how to do that in Ubuntu::
 
-    sudo apt-get install language-pack-en language-pack-es
+    sudo apt-get install language-pack-en language-pack-pl
+
