Update current translations, and add new languages:
- es_MX: Spanish (Mexico)
- pam: Kapampangan
Also update translation process for autoconf-based build system.
- update translation master files
- include current translations from Transifex
- add several new languages
- fix a bug in bitcoin.qrc, which prevents some languages from beeing used
(wrong file extension .ts instead of .qm was used)
why:
- the current splash-screen has no referring to official images on - https://en.bitcoin.it/wiki/Promotional_graphics
- the current splash screen only exists in a low res jpg
- current splash screen looks dark and "hackish"
- new splash screen should generate positive, "trust-emotions".
- new splash screen gives the user infos about the running client.
- new splash screen can handle long messages (in a lot of - languages the text is cropped in current release)
- new size (x2) 400x312
- contains textual information about the client
- textinfos are dynamicly written to the pixmap
when -testnet is switch on, the splashscreen will show the bitcoin logo in testnet-color (as well as a text [testnet])

- added languages in bitcoin.qrc: bs, ca, cy, eo, gu_IN, hi_IN, ja, la,
lv_LV and th_TH (some translations files were already in src/qt/locale
but not added in the .qrc file
- try to enforce the same style to all Qt related files
- remove unneeded includes from the files
- add missing Q_OBJECT, QT_BEGIN_NAMESPACE / QT_END_NAMESPACE
- prepares for a pull-req to include Qt5 compatibility
- icon from the LGPL Nuvola set (like the tick) - http://www.icon-king.com/projects/nuvola/
- include 'boost/version.hpp' in db.cpp so that the overwrite version of copy can be used
- catch exceptions in BackupWallet (e.g. filesystem_error thrown when trying to overwrite without the overwrite flag set)
- include db.h in walletmodel.cpp for BackupWallet function
- updated doc/assets-attribution.txt and contrib/debian/copyright with copyright info for new icon
- use wildcard for TRANSLATIONS in bitcoin-qt.pro to automatically build all translations present in src/qt/locale (thanks @tcatm)
- first load translations/<language>.qm, then translations/<language>_<TERRITORY>.qm, so that territory-specific translations take precedence, but the fallback is on the base language if no territory-specific translation exists.
- use wildcard for TRANSLATIONS in bitcoin-qt.pro to automatically build all translations present in src/qt/locale (thanks @tcatm)
- rename language files to the usual <lang>_<TERRITORY>
- include recently added language files for es_ES and nb_NO
