PCSX2 SVN r4509 is released. PCSX2 is an open source PlayStation 2 (PS2) emulator for the Microsoft Windows and Linux operating systems. With the most recent versions, many PS2 games are playable (although speed limitations have made play-to-completion tests for many games impractical), and several games are claimed to have full functionality.

PCSX2 SVN Changelog:
r4505
GSdx: 5-10% speedup in multi-threaded mode, replaced that modulo operator with a lookup table.
r4506
Suppress expected error during first time wizard when a plugin does not implement optional API functions.
r4507
Portable mode: now allows fully custom folders, but still allows relocation of pcsx2 folder without breaking (install mode unmodified).

Details:
The major differences between install and portable modes should now be:
1. Portable mode doesn't use the registry at all.
2. Portable mode uses the folders inside pcsx2 folder as default (install mode has some default at "my documents").
3. Portable mode tries to save relative paths at the ini file where possible*.

Specifically, portable mode now allows to select custom folders for plugins, bios, etc via the standard UI, which allows using several portable pcsx2 folder sharing the same resources (bios, iso, memcards, etc).

* Relative paths where possible = the following sequence (thanks to pseudonym for the brilliant idea):
1. If the file/folder is inside pcsx2 folder, it's saved as completely relative (to pcsx2.exe)
2. Else, if the file/folder is at the same drive as pcsx2.exe, it's saved as absolute path without the drive letter (e.g. /ISO/...)
3. Else, saved as absolute path, including the drive letter (for linux, without drive letter naturally).

This allows to create a removable drive with (one or more) pcsx2 folder on it, configure all the files/folders to point to the same drive (ISOs, save states, etc), and then take this drive, plug it into another computer (where it will be assigned with a different drive letter), and everything will continue working.

Please test it if you can. Bugs here can be inconvenient...
r4508
Made the uninstaller nicer / removed some unused stuff.
The uninstaller now removes all PCSX2 paths info, so that a reinstall works as expected.
It also offers to remove plugin configuration files and user created files separately.
r4509
i18n: add some missing strings. Remove SetDiagMsg one.
