Implement customizable cache timeout (#641)

Browse Source 
* [BridgeAbstract] Implement customizable cache timeout

The customizable cache timeout is used instead of the default cache
timeout (CACHE_TIMEOUT) if specified by the caller.

* [index] Add new global parameter '_cache_timeout'

The _cache_timeout parameter is an optional parameter that can be
used to specify a custom cache timeout. This option is enabled by
default.

It can be disabled using the named constant 'CUSTOM_CACHE_TIMEOUT'
which supports two states:

> true: Enabled (default)
> false: Disabled

* [BridgeAbstract] Change scope of 'getCacheTimeout' to public

* [html] Add cache timeout parameter to all bridges

The timeout parameter only shows if CUSTOM_CACHE_TIMEOUT has been set
to true. The default value is automatically set to the value specified
in the bridge.

* [index] Disable custom cache timeout by default
