New strings and slight UI change in Anjuta

[Naba Kumar <naba kumar gmail com>]

Hello,

We introduced a few new strings in Anjuta master branch:

New strings:

1. "Install missing packages". commit: 	53ca6b8f5875e64fe3641b687e37dc7d7d87de54

2. "The \"%s\" package is not installed.\nPlease install it.",
package_name. commit: 	d9f043bdbcb3ce8add3d641eadcaafbc240fc02e

3. "You do not seem to have PackageKit installed. PackageKit is
required for installing missing packages. Please install
\"packagekit-gnome\" package from your distribution, or install the
missing packages manually.". commit:
	f3fa52aaddddc4082c41bdbf93def80f05d624db

4. "Installation failed: %s", error_message.  commit:
	f3fa52aaddddc4082c41bdbf93def80f05d624db

UI Change:

There is also a small UI change. There is now a button labeled
"Install missing packages" at bottom-right corner of warning druid
page for missing packages in project creation wizard
(File->New->Project). When user clicks it, it either asks packagekit
to install the missing packages, or show an error dialog if packagekit
is missing or there was an error in invoking it.

Thanks.
