Can't start BootManager

[idefix]

Installer won't start BootManager when the mime-info database isn't updated.

Steps to reproduce:

1. Download an R1 Alpha3 RC cd-image (eg. ​haiku-r1a3-rc-r41789-cd.tar.xz)
2. Boot from the cd
3. Choose Run Installer in ReadOnlyBootPrompt
4. Select Tools - Set up boot menu
5. You get a warning stating "Bootman, the application to configure the Haiku boot menu, could not be launched."

To fix this, the code in InstallerWindow.cpp should be changed to search for BootManager in the apps folder.

Also, the warning should read "BootManager, the application to configure the Haiku boot menu, could not be launched."

The attached patch​ should fix it. (Not tested yet. Tested with R1/alpha3 hrev41789.)

Would updating the warning text from "Bootman" to "BootManager" partially break Installer's catalog files?

[humdinger]

"Break" is too hard a word. It'll invalidate the string and add a new one that needs to be translated again. Which is more or less a copy&paste thing. As it looks like alpha3 is delayed a while longer, that's no problem whatsoever, I think.

Applied in hrev41837, thanks a lot!

R1 Alpha 3 has not yet been released. This was with an R1 Alpha 3 Release Candidate image.
