Introduced _patchLog() and logMsg attribute to unify the logs
Using logMsg extracted common buildPatchLog for six C patchers
_clog() method in buildPatchLog and one more _patchLog
Renames in class attributes so patchers compare better and more:

- self.srcFiles, self.sourceMods --> self.sourceMods in import patchers
- new parameters in _patchLog()

I need to somehow unify this mess.
Added _plog() in P patchers and more:

More logs unified.
Added some marker TODOs.
Added suppress warnings for unused variables that are (apparently) used to
trigger the GC.
Notice:

- faceMods -> sourceMods
- _(u'Source Mods/Files') vs _(u'Source Mods') // kept this...
- Attribute self.class_mod_count renamed to self.mod_count (gosh I hate this
kind of differences)
More self.class_mod_count renamed to self.mod_count + some formatting
New method CBash_ImportPatcher._srcMods() - to better unify the logs:

_(u'Source Mods/Files') may have its uses...
Rest of logging todos
The six patchers that do not override _clog - removing u'* ':

+ CBash_DeathItemPatcher that calls it as super()._clog
Notice this points to a pattern:
        self._srcMods(log)
        super(CBash_DeathItemPatcher, self)._clog(log)
maybe more clogs are like this
Also CBash_ImportInventory - I used logMsg prematurely (will be fixed later)
Types of _clog loggers classification:

All Import patchers are 17 !

_clog:

- type 11 (2): log(u'\n=== ' + _(u'Modified Records'))
- type 1 (4): log(u'\n=== ' + _(u'VARIES')) +  _(u'Source Mods/Files')
- type 12 (2): like 1 but no _srcMods
- type 2 (3): _srcMods + a call of base _clog (super._clog)
- 6 patchers do not override the base

Notice that the 1 types have u'YYY %s Records: %d' - need dicts for format
strings!
TODO: extract module methods (done in the importers-rip branch)
Translatable strings - removed %d:

Search for
_\(u'[^%)]*[%][a-zA-Z]
_\(u'[^%)]*[%]
and (surprise) for _\('[^%)]*[%]
// notice I omitted u
Merge branch 'utumno-importer_logs' into dev:

Introducing _patchLog, _plog for P patchers and _clog method for C
patchers as well as logMsg class attriibute to unify the logs. Some
renaming of class attributes was necessary.
Also format strings are moved out of translatable strings (see #55).
In the importers-rip branch further refactoring of the logs takes place.
