Bug 516933 – Rewrite attachment UI
Rewrite the attachment UI to better utilize GIO and also to migrate from GnomeIconList to GtkIconView. This also introduces a "List View" option similar to Nautilus, as well as the EAttachmentHandler framework for extending attachment handling (may eventually replace EMFormatHook). This commit also fixes a number of secondary attachment bugs: Bug 311609 – new attachment bar should use regular gtk+ expander Bug 314923 – Drag and Drop in attachment window is inconsistent and requires additional click Bug 338179 – attachment saving ... Bug 350364 – Action to get info about attachments Bug 383047 – Viewing mail attachments Bug 427235 – Can't copy attachment mime type string Bug 454091 – Cannot save multiple attachments who have the same name Bug 494629 – Rethink composer's attachment UI Bug 553970 – Evolution ignores umask when saving attachments Bug 577375 – mailto: and attach doesn't URL un-escape
