blockchain -> block chain (used everywhere else)
Move GenerateBitcoins() call out of net.cpp's StartNode()

The internal miner is closely bound to the wallet engine,
not the blockchain engine.
Words in English language are more short than in other langs usually.
Tabs don't fits in line in Spanish/German/Russian when they has two words.
Wallet has limited functionality. It can send & receive coins. So we can
safely rename "Send coins" to "Send" and "Receive coins" to "Receive".
Address book is just stored addresses.
qt: remove transaction count from overview page

It was needlessly confusing people, as it doesn't necessarily match the
number of transactions in the transaction list.
Merge pull request #2433 from laanwj/2013_03_removetransactioncount

Remove transaction count from overview page
fix "send coins" via context menu in address book

- the send coins context menu entry was not working anymore, because
  a non current version of #2220 was merged onto current master
- also removes some unneeded spaces and adds a comment to
  WalletModel::getNumTransactions()
Bitcoin-Qt: fix debug window

- fix debug window, by re-adding rpcConsole->setClientModel(clientModel);
  in BitcoinGUI::setClientModel(), which was removed by #2220

Revert "Actually use mapAlreadyAskedFor."

This reverts commit 643160f6e7e5e8ca84bc7d2c1a0f37d9cf43a6e1.

Turns out this commit was useless after a more careful reading of
CNode::AskFor
Add a limitedmap class similar to mruset
Move mapAlreadyAskedFor to limitedmap

This will result in re-requesting invs if we are under heavy inv
load, however as long as we get no more than 16,000 invs in two
minutes, this should have no effect on runtime behavior.
Merge pull request #2428 from r000n/staging

Simplify titles of tabs in main window
Bitcoin-Qt: fix copy via context-menu broken

- as QClipboard::Selection isn't available on Windows ensure that the
  correct mode is called, but sill allow selection for e.g. X11
- start conversion from QCoreApplication::instance() to qApp in
  guiutil.cpp (I intend to harmonize this all over the source with my Qt5
  compatibility pull)
translation base files update 2013-04-02

- also includes a small change to a string in bitcoinrpc.cpp, which is not
  on Transifex anyway, so is safe to merge
