Subject: [PATCH] Reload preload engines until users customize the list.

This patch was generated by ftake@geeko.jp from a git repository maintained by
a upstream developer (fujiwarat).
https://github.com/fujiwarat/ibus/commits/gtk3-vala

The following description is from the original commit:

The idea is, if users don't customize the preload_engines with ibus-setup,
users would prefer to load the system default engines again by login.
The gconf value 'preload_engine_mode' is
IBUS_PRELOAD_ENGINE_MODE_USER by default but set
IBUS_PRELOAD_ENGINE_MODE_LANG_RELATIVE for the initial login.
If preload_engine_mode is IBUS_PRELOAD_ENGINE_MODE_LANG_RELATIVE,
ibus-daemon loads the system preload engines by langs.
If preload_engine_mode is IBUS_PRELOAD_ENGINE_MODE_USER,
ibus-daemon do not update the gconf value preload_engines.
On the other hand, if users enable the customized engine checkbutton
on ibus-setup, ibus-setup sets 'preload_engine_mode' as
IBUS_PRELOAD_ENGINE_MODE_USER and users can customize the value
'preload_engines'.
