Limit the impact of reorganisations on the database (fix #925)

Sometimes a new block arrives in a new chain that was already the
best valid one, but wasn't marked that way. This happens for example
when network rules change to recover after a fork.

In this case, it is not necessary to do the entire reorganisation
inside a single db commit. These can become huge, and exceed the
objects/lockers limits in bdb. This patch limits the blocks the
actual reorganisation is applied to, and adds the next blocks
afterwards in separate db transactions.

Resolves issue #922 - "wallet passphrase timeout of several years doesn't work"

2^31 milliseconds is only about 25 days. Also clamps Sleep() to 10 years,
because it currently sleeps for 0 seconds when the sleep time would cross
2^31 seconds since the epoch. Hopefully boost will be fixed by 2028.

fix typo src/net.cpp

Do not allow overwriting unspent transactions

Introduce the following network rule:
 * a block is not valid if it contains a transaction whose hash
   already exists in the block chain, unless all that transaction's
   outputs were already spent before said block.

Warning: this is effectively a network rule change, with potential
risk for forking the block chain. Leaving this unfixed carries the
same risk however, for attackers that can cause a reorganisation
in part of the network.

Move 'Backup Wallet' to file menu

Before 0.6 addrProxy was a CAddress, but netbase changed it to CService.
Retain compatibility by wrapping/unwrapping with a CAddress when saving
or loading.

This commit retains compatibility with 0.6.0rc1 (which wrote the setting
as a CService) by trying to parse twice.

In UI, handle cases in which the last received block was generated in the future

Fixes #874.

Doing so would allow an attack on old nodes, which would relay a
standard transaction spending a BIP16 output in an invalid way,
until reaching a new node, which will disconnect their peer.
