(svn r9471) [0.5] -Backport from trunk (r9467 & r9469):
Reset the whole currency array while preserving custom one. Also, max data of to_euro is now 300, not 1000, disabling any proper loading of the patch setting

(svn r9430) [0.5] -Backport r9429: when deleting a vehicle which has shared orders with one more vehicle and no orders, segfaulted

(svn r9422) [0.5] -Prepare 0.5 branch for release of 0.5.1-RC2.

(svn r9421) [0.5] -Backport from trunk (r9392, r9415, r9420, custom):

(svn r9358) [0.5] -Backport from trunk (r9055, r9082, r9083, r9084, r9085, r9086):
- Codechange: Change windows unicode handling and allow a pure non-unicode build to function. (r9055)
- Codechange: [win32] Update VS2003 and VS2005 project files to build in UNICODE mode. When making a release it is probably better to make two binaries, one without UNICODE, the other with, guaranteeing full Win9x compatibility (UNICODE with MSLU also works, without it's even better). (r9082)
- Codechange: Be more lenient when trimming UTF-8 strings and don't terminate the string when an invalid encoding is encountered, but only focus on maximum length. (r9083)
- Fix: [win9x] Clipboard paste for Windows95 (doesn't have CF_UNICODETEXT) correctly converts the input to the current locale. (r9084)
- Fix: [win32] Move the initialisation of _codepage (non-UNICODE) to winMain as a dedicated server, or different video driver will not have a win32 messageloop. (r9085)
- Fix: [win32] Rewrite keyboard input and handle all keypresses in a WM_CHAR event. This saves us from doing translation (ToUnicode[Ex], ToAscii[Ex]), and we get free IME-input support as a plus. (r9086)

(svn r9355) [0.5] -Backport from trunk (r8906):
- Feature: translation dependant formatting of dates (r8906)

-Regression: [win32] Possible buffer overflow if unicode text is pasted into an input box and needs trimming. (r8975)
-Codechange: Introduce a function Utf8PrevCharLen that finds the starting character of an UTF-8 sequence from a given position and returns the length to the first UTF-8 encoding byte of that sequence. (r9003)
-Codechange: Rework Utf8PrevChar so that it returns a pointer to the previous UTF8 character's first byte instead of a byte-length offset (r9011)
-Fix: When cutting strings into multiple lines also take into consideration whitespace characters of more than 1 byte length (eg IDEOGRAPHIC SPACE, IsWhitespace() function). When trimming such strings, account for multiple-byte long sequences so use *Utf8PrevChar(v) = '\0'. (r9012)
-Codechange: Add a function Utf8TrimString() that properly trims a string to an UTF8 encoding seperation instead of somewhere in the wild (and use it in the chat area) (r9012)

(svn r9350) [0.5] -Backport from trunk (r9105, r9115, r9117, r9146):
- Fix: disable the ability to make flooding water with the canal build tool. In the scenario editor you can still make both canals and flooding water at height level 0 (r9105)

- Fix: don't keep on scrolling for non-numeric values in settings, but require reclick (r9064)
